* ARM: pxa: spitz: Open code gpio_request_array()Andy Shevchenko2024-04-031-10/+12
| | | | | | | | | In order to prerare for removal of gpio_request_array(), open code the latter. Note, we are not using gpio_request_one() as it's also deprecated, hence reducing legacy API usage to the very basic ones.

* ARM: pxa: fix missing-prototypes warningsArnd Bergmann2023-05-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The PXA platform has a number of configurations that end up with a warning like these when building with W=1: drivers/hwmon/max1111.c:83:5: error: no previous prototype for 'max1111_read_channel' [-Werror=missing-prototypes] arch/arm/mach-pxa/reset.c:86:6: error: no previous prototype for 'pxa_restart' [-Werror=missing-prototypes] arch/arm/mach-pxa/mfp-pxa2xx.c:254:5: error: no previous prototype for 'keypad_set_wake' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa25x.c:70:14: error: no previous prototype for 'pxa25x_get_clk_frequency_khz' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa25x.c:325:12: error: no previous prototype for 'pxa25x_clocks_init' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa27x.c:74:14: error: no previous prototype for 'pxa27x_get_clk_frequency_khz' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa27x.c:102:6: error: no previous prototype for 'pxa27x_is_ppll_disabled' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa27x.c:470:12: error: no previous prototype for 'pxa27x_clocks_init' [-Werror=missing-prototypes] arch/arm/mach-pxa/pxa27x.c:44:6: error: no previous prototype for 'pxa27x_clear_otgph' [-Werror=missing-prototypes] arch/arm/mach-pxa/pxa27x.c:58:6: error: no previous prototype for 'pxa27x_configure_ac97reset' [-Werror=missing-prototypes] arch/arm/mach-pxa/spitz_pm.c:170:15: error: no previous prototype for 'spitzpm_read_devdata' [-Werror=missing-prototypes] The problem is that there is a declaration for each of these, but it's only seen by the caller and not the callee. Moving these into appropriate header files ensures that both use the same calling conventions and it avoids the warnings.

* ARM: pxa: split up mach/hardware.hArnd Bergmann2022-04-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mach/hardware.h is included in lots of places, and it provides three different things on pxa: - the cpu_is_pxa* macros - an indirect inclusion of mach/addr-map.h - the __REG() and io_pv2() helper macros Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h headers, then change all the files that use mach/hardware.h to include the exact set of those three headers that they actually need, allowing for further more targeted cleanup. linux/soc/pxa/cpu.h can remain permanently exported and is now in a global location along with similar headers. pxa-regs.h and addr-map.h are only used in a very small number of drivers now and can be moved to arch/arm/mach-pxa/ directly when those drivers are to pass the necessary data as resources.

* ARM: pxa: fix GPIO double shiftsRobert Jarzmik2016-09-091-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 9bf448c66d4b ("ARM: pxa: use generic gpio operation instead of gpio register") from Oct 17, 2011, leads to the following static checker warning: arch/arm/mach-pxa/spitz_pm.c:172 spitz_charger_wakeup() warn: double left shift '!gpio_get_value(SPITZ_GPIO_KEY_INT) << (1 << ((SPITZ_GPIO_KEY_INT) & 31))' As Dan reported, the value is shifted three times : - once by gpio_get_value(), which returns either 0 or BIT(gpio) - once by the shift operation '<<' - a last time by GPIO_bit(gpio) which is BIT(gpio) Therefore the calculation lead to a chained or operator of : - (1 << gpio) << (1 << gpio) = (2^gpio)^gpio = 2 ^ (gpio * gpio) It is be sheer luck the former statement works, only because each gpio used is strictly smaller than 6, and therefore 2^(gpio^2) never overflows a 32 bits value, and because it is used as a boolean value to check a gpio activation. As the xxx_charger_wakeup() functions are used as a true/false detection mechanism, take that opportunity to change their prototypes from integer return value to boolean one.

| | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers.

* ARM: pxa/spitz_pm: Fix hang when resuming from STRMarko Katic2012-10-281-6/+2
| | | | | | | | | | | | | | | | 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.

Therefore, we should not be unconditionally writing to RCSR from generic code.
