| | | | | | | | | | Although the GPIO alternate functions should be correctly set by the bootloader, configure them here to be sure. To save power, FFUART/BTUART/STUART are left unconfigured (output, low) until they are needed by pxaficp or the magician GSM chipset driver.

* [ARM] pxa: add partial keypad support for mainstoneeric miao2008-04-19
| | | | | | | | | | | | | | This is partial because mainstone's keypad is really special, some of the keys like '1', '2', ... are actually connected to two row/column juntions, thus pressing '1' is equivalent to pressing 'A' & 'H'. This is really brain damanged since it makes distinguishing between pressing '1' and multiple keys pressing of 'A' & 'H' difficult. So these special keys are not supported for the time being.

* [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: use new pin configuration mechanism for mainstoneeric miao2008-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | 1. the following code to configure PGSRx is no way portable and intuitive: - PGSR0 = 0x00008800; - PGSR1 = 0x00000002; - PGSR2 = 0x0001FC00; - PGSR3 = 0x00001F81; this is removed as low power state has already been encoded in the pin configuration definitions. Note: there is no specific reason for some of the GPIOs to drive high in low power mode as indicated by the above setting, those bits are ignored, and the result is validated to work. 2. the following code to configure GPIO wakeup is removed as this is now totally handled by pxa2xx_mfp_config(): - PWER = 0xC0000002; - PRER = 0x00000002; - PFER = 0x00000002; 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: make pxa_gpio_irq_type() processor genericeric miao2008-04-19
| | | | | | | | | | | | | | | | | | The main issue here is that pxa3xx does not have GAFRx registers, access directly to these registers should be avoided for pxa3xx: 1. introduce __gpio_is_occupied() to indicate the GAFRx and GPDRx registers are already configured on pxa{25x,27x} while returns 0 always on pxa3xx 2. pxa_gpio_mode(gpio | GPIO_IN) is replaced directly with assign- ment of GPDRx, the side effect of this change is that the pin _must_ be configured before use, pxa_gpio_irq_type() will not change the pin to GPIO, as this restriction is sane, esp. with the new MFP framework 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>
