* ARM: pxa/spitz_pm: Fix hang when resuming from STRMarko Katic2012-10-27
| | | | | | | | | | | | | | | | Devices that use spitz_pm.c will fail to resume from STR (Suspend To Ram) when the charger plug is inserted or removed when a device is in STR mode. The culprit is a misconfigured gpio line - GPIO18. GPIO18 should be configured as a regular GPIO input but it gets configured as an alternate function GPIO18_RDY. And then later in postsuspend() it gets configured as a regular GPIO18 input line. Fix this by removing the GPIO18_RDY configuration so that GPIO18 only gets configured as a regular gpio input.

* gpio: include linux/gpio.h where neededRandy Dunlap2011-06-16
| | | | | | | | | Some files use GPIOF_ macros but don't include the header file for them. These macros are being moved to <linux/gpio.h>, so add includes for <linux/gpio.h> where needed. Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

* [ARM] pxa: use generic gpio_get_value() instead of READ_GPIO_BIT()Eric Miao2010-08-05
| | | | | | | READ_GPIO_BIT() is no way generic by accessing GPIO registers directly, replace it with gpio_get_value(). Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
* [ARM] pxa: removing dead BACKLIGHT_CORGIChristoph Egger2010-08-05
| | | | | | | | | BACKLIGHT_CORGI was later renamed to BACKLIGHT_GENERIC and has not been used since then. As it's now safe to completely transition to LCD_CORGI driver, which incorprates both the LCD and backlight device.

* [ARM] pxa/spitz: use generic GPIO API and remove pxa_gpio_mode()Eric Miao2010-05-11
| | | | | | | | REVISIT: change to GPIO18 is ugly, need to make sure whether that's really necessary - GPIO18_RDY as an VLIO input signal - we don't normally need to do such kind of trick during low power mode. Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

* [ARM] pxa/sharpsl_pm: merge pxa-specific code into generic oneDmitry Eremin-Solenikov2009-06-11

* [ARM] pxa: separate definitions from pxa-regs.h and remove it finallyEric Miao2009-03-09
| | | | | | | | | | | | | | | | | | | The remaining registers are separated into: - <mach/regs-ost.h> - <mach/regs-rtc.h> - <mach/regs-intc.h> and then we can remove pxa-regs.h completely. Instead of #include this file, let's: 1. include the specific <mach/regs-*.h> with care (if that's absolutely necessary) 2. define the registers in the driver, make cleanly defined API to expose the register access to external with sufficient reason Signed-off-by: Eric Miao <eric.miao@marvell.com>

* [ARM] pxa: corgibl_limit_intensity build errorsRussell King2008-05-19
| | | | | | | | | | | | If CONFIG_BACKLIGHT_CORGI is not selected, then corgibl_limit_intensity() is not present. However, both corgi_pm.c and sharp_pm.c reference this symbol, resulting in a link error. Wrap the references with the relevant ifdefs, and avoid the resulting NULL pointer dereference by making the code in sharpsl_pm.c also conditional on the config symbol.

* [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.

* [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>
