* [ARM] pxa: Fix RCSR handlingRussell King2008-05-08
| | | | | | | | | | | | | | Related to d3930614e68bdf83a120d904c039a64e9f75dba1. RCSR is only present on PXA2xx CPUs, not on PXA3xx CPUs. Therefore, we should not be unconditionally writing to RCSR from generic code. Since we now clear the RCSR status from the SoC specific PXA PM code and before reset in the arch_reset() function, the duplication in the corgi, poodle, spitz and tosa code can be removed.

| | | | | | | | | | | Each time a pxa type cpu went in suspend, a portion of kmalloc memory was corrupted. The issue was an incorrect length allocation introduced by the commit 711be5ccfe9a02ba560aa918a008c31ea4760163 for the save registers array (=> overflow).

* pxafb: introduce register independent LCD connection type for pxafberic miao2008-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | Reasons: 1. straight forward: the name "LCD_COLOR_DSTN_16BPP" is much better than "LCCR0_Pas | LCCR0_Color | LCCR0_Dual" 2. by defining LCD connection types as constants, it allows only valid possibilities 3. by removing the dependency of register bits definitions, those can be later moved into the body of pxafb.c, instead of having a regs-lcd.h around Currently, only lubbock, mainstone, zylonite and littleton have been modified to support these types (see coming patches after this). Other platforms are encouraged to change their way describing the LCD controller connections. Signed-off-by: eric miao <eric.miao@marvell.com> Cc: "Antonino A.

* pxafb: convert fb driver to use ioremap() and __raw_{readl, writel}eric miao2008-04-30
| | | | | | | | | | | | | | | | | | This is part of the effort moving peripheral registers outside of pxa-regs.h, and using ioremap() make it possible the same IP can be re-used on different processors with different registers space As a result, the fixed mapping in pxa_map_io() is removed. The regs-lcd.h can actually moved to where closer to pxafb.c but some of its bit definitions are directly used by various platform code, though this is not a good style.

* / [MTD] [NAND] support for pxa3xxeric miao2008-04-22
|/ | | | | | | | | | | | | | | | | | | | | | | | | | This is preliminary since: 1. It supports only _one_ chip select at the moment. As there is no existing platforms available using two chip selects of the NAND controller, it shall really not include code for supporting the 2nd chip select for now, as such code cannot be verified. 2. It resorts to the default and simpliest memory based badblock table 3. Only limited types of nand flash are currently supported. Most PXA3xx processors come with on-chip NAND flash dies, so there isn't much flexibility for other types of NAND. 4. The NAND controller should be configured to detect the device's ID, thus making it difficult to use nand_scan_ident() to assist the detection process (though it's not impossible) TODO: fix all the above limitations of cuz :-) Signed-off-by: eric miao <eric.miao@marvell.com> Cc: Sergey Podstavin <spodstavin@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* [ARM] pxa: allow dynamic enable/disable of GPIO wakeup for pxa{25x,27x}eric miao2008-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes include: 1. rename MFP_LPM_WAKEUP_ENABLE into MFP_LPM_CAN_WAKEUP to indicate the board capability of this pin to wakeup the system 2. add gpio_set_wake() and keypad_set_wake() to allow dynamically enable/disable wakeup from GPIOs and keypad GPIO * these functions are currently kept in mfp-pxa2xx.c due to their dependency to the MFP configuration 3. pxa2xx_mfp_config() only gives early warning if MFP_LPM_CAN_WAKEUP is set on incorrect pins So that the GPIO's wakeup capability is now decided by the following: a) processor's capability: (only those GPIOs which have dedicated bits within PWER/PRER/PFER can wakeup the system), this is initialized by pxa{25x,27x}_init_mfp() b) board design decides: - whether the pin is designed to wakeup the system (some of the GPIOs are configured as other functions, which is not intended to be a wakeup source), by OR'ing the pin config with MFP_LPM_CAN_WAKEUP - which edge the pin is designed to wakeup the system, this may depends on external peripherals/connections, which is totally board specific; this is indicated by MFP_LPM_EDGE_* c) the corresponding device's (most likely the gpio_keys.c) wakeup attribute: Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] pxa: add MFP-alike pin configuration support for pxa{25x, 27x}eric miao2008-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pin configuration on pxa{25x,27x} has now separated from generic GPIO into dedicated mfp-pxa2xx.c by this patch. The name "mfp" is borrowed from pxa3xx and is used here to alert the difference between the two concepts: pin configuration and generic GPIOs. A GPIO can be called a "GPIO" _only_ when the corresponding pin is configured so. A pin configuration on pxa{25x,27x} is composed of: - alternate function selection (or pin mux as commonly called) - low power state or sleep state - wakeup enabling from low power mode The following MFP_xxx bit definitions in mfp.h are re-used: - MFP_PIN(x) - MFP_AFx - MFP_LPM_DRIVE_{LOW, HIGH} - MFP_LPM_EDGE_* Selecting alternate function on pxa{25x, 27x} involves configuration of GPIO direction register GPDRx, so a new bit and MFP_DIR_{IN, OUT} are introduced. And pin configurations are defined by the following two macros: - MFP_CFG_IN : for input alternate functions - MFP_CFG_OUT : for output alternate functions Every configuration should provide a low power state if it configured as output using MFP_CFG_OUT(). As a general guideline, the low power state should be decided to minimize the overall power dissipation. As an example, it is better to drive the pin as high level in low power mode if the GPIO is configured as an active low chip select. Pins configured as GPIO are defined by MFP_CFG_IN(). This is to avoid side effects when it is firstly configured as output. The actual direction of the GPIO is configured by gpio_direction_{input, output} Wakeup enabling on pxa{25x, 27x} is actually GPIO based wakeup, thus the device based enable_irq_wake() mechanism is not applicable here. E.g. invoking enable_irq_wake() with a GPIO IRQ as in the following code to enable OTG wakeup is by no means portable and intuitive, and it is valid _only_ when GPIO35 is configured as USB_P2_1: enable_irq_wake( gpio_to_irq(35) ); To make things worse, not every GPIO is able to wakeup the system. Only a small number of them can, on either rising or falling edge, or when level is high (for keypad GPIOs). Thus, another new bit is introduced to indicate that the GPIO will wakeup the system: - MFP_LPM_WAKEUP_ENABLE The following macros can be used in platform code, and be OR'ed to the GPIO configuration to enable its wakeup: - WAKEUP_ON_EDGE_{RISE, FALL, BOTH} - WAKEUP_ON_LEVEL_HIGH The WAKEUP_ON_LEVEL_HIGH is used for keypad GPIOs _only_, there is no edge settings for those GPIOs. These WAKEUP_ON_* flags OR'ed on wrong GPIOs will be ignored in case that platform code author is careless enough. The tradeoff here is that the wakeup source is fully determined by the platform configuration, instead of enable_irq_wake().

* [ARM] pxa: separate GPIOs and their mode definitions to pxa2xx-gpio.heric miao2008-04-19
| | | | | | | | | | | | | two reasons: 1. GPIO namings and their mode definitions are conceptually not part of the PXA register definitions 2. this is actually a temporary move in the transition of PXA2xx to use MFP-alike APIs (as what PXA3xx is now doing), so that legacy code will still work and new code can be added in step by step Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into oneeric miao2008-04-19
| | | | | | | | | | | | | | | | | | | | | This makes the code better organized and simplified a bit. The change will lose a bit of performance when performing IRQ ack/mask/unmask,but that's not too much after checking the result binary. This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by carefully not to access those pxa{27x,3xx} specific registers, this is done by keeping an internal IRQ number variable. The pxa-regs.h is also modified so registers for IRQ > PXA_IRQ(31) are made public even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake) The incorrect assumption in the original code that internal irq starts from 0 is also corrected by comparing with PXA_IRQ(0). "struct sys_device" for the IRQ are reduced into one single device on pxa{27x,3xx}. Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* spi: pxa2xx_spi clock polarity fixNed Forrester2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | Fixes a sequencing bug in spi driver pxa2xx_spi.c in which the chip select for a transfer may be asserted before the clock polarity is set on the interface. As a result of this bug, the clock signal may have the wrong polarity at transfer start, so it may need to make an extra half transition before the intended clock/data signals begin. (This probably means all transfers are one bit out of sequence.) This only occurs on the first transfer following a change in clock polarity in systems using more than one more than one such polarity. The fix assures that the clock mode is properly set before asserting chip select. This bug was introduced in a patch merged on 2006/12/10, kernel 2.6.20. The patch defines an additional bit in: include/asm-arm/arch-pxa/regs-ssp.h for 2.6.25 and newer kernels but this addition must be made in: include/asm-arm/arch-pxa/pxa-regs.h for kernels between 2.6.20 and 2.6.24, inclusive Signed-off-by: Ned Forrester <nforrester@whoi.edu> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Cc: Russell King <rmk@arm.linux.org.uk> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | gpiolib support for the PXA architecturePhilipp Zabel2008-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds gpiolib support for the PXA architecture: - move all GPIO API functions from generic.c into gpio.c - convert the gpio_get/set_value macros into inline functions This makes it easier to hook up GPIOs provided by external chips like ASICs and CPLDs.

| | | | | | | | | | | | | | | | | | | | | | | | This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.
