* pinctrl: use devm_platform_ioremap_resource() to simplify codeYueHaibing2019-11-051-3/+1
| | | | | | | | | | | | | | | devm_platform_ioremap_resource() internally have platform_get_resource() and devm_ioremap_resource() in it. So instead of calling them separately use devm_platform_ioremap_resource() directly.

This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

* pinctrl: Widen the generic pinconf argument from 16 to 24 bitsMika Westerberg2017-01-261-5/+5
| | | | | | | | | | | | | | | | | | | | The current pinconf packed format allows only 16-bit argument limiting the maximum value 65535. For most types this is enough. However, debounce time can be in range of hundreths of milliseconds in case of mechanical switches so we cannot represent the worst case using the current format. In order to support larger values change the packed format so that the lower 8 bits are used as type which leaves 24 bits for the argument. This allows representing values up to 16777215 and debounce times up to 16 seconds. We also convert the existing users to use 32-bit integer when extracting argument from the packed configuration value.

* pinctrl: lpc18xx: make it explicitly non-modularPaul Gortmaker2016-06-131-17/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: config PINCTRL_LPC18XX bool "NXP LPC18XX/43XX SCU pinctrl driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

* pinctrl: lpc18xx: add nxp,gpio-pin-interrupt propertyJoachim Eastwood2016-03-071-6/+137
| | | | | | | | | | | | | | | Add support for setting up GPIO pin interrupts in the lpc18xx pinctrl driver. The LPC18xx SCU contain two registers that sets up the signal routing to the GPIO pin interrupt (PINT) block. The routing uses the GPIO namespace and not the pin namespace so a lookup is preformed on the pin. Routing configuration is done in the device tree by using the new nxp,gpio-pin-interrupt property. This property takes single parameter which sets the PINT hwirq for the GPIO. Signed-off-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Like with GPIO it's a lot of stuff. If my subsystems are any sign of the overall tempo of the kernel v4.3 will be a gigantic diff. [ It looks like 4.3 is calmer than 4.2 in most other subsystems, but we'll see - Linus ] Core changes: - It is possible configure groups in debugfs. - Consolidation of chained IRQ handler install/remove replacing all call sites where irq_set_handler_data() and irq_set_chained_handler() were done in succession with a combined call to irq_set_chained_handler_and_data(). This series was created by Thomas Gleixner after the problem was observed by Russell King. - Tglx also made another series of patches switching __irq_set_handler_locked() for irq_set_handler_locked() which is way cleaner. - Tglx also wrote a good bunch of patches to make use of irq_desc_get_xxx() accessors and avoid looking up irq_descs from IRQ numbers. The goal is to get rid of the irq number from the handlers in the IRQ flow which is nice. Driver feature enhancements: - Power management support for the SiRF SoC Atlas 7. - Power down support for the Qualcomm driver. - Intel Cherryview and Baytrail: switch drivers to use raw spinlocks in IRQ handlers to play nice with the realtime patch set. - Rework and new modes handling for Qualcomm SPMI-MPP. - Pinconf power source config for SH PFC.
