linux/drivers/pinctrl, branch v3.11

pinctrl: sunxi: Add spinlocks

2013-08-07T19:57:17Z

The current code use no locking at all, which is obviously not that great and can lead to concurrency issues, especially with the newer SMP SoCs from Allwinner. Add some locking where it's needed. Signed-off-by: Maxime Ripard Signed-off-by: Linus Walleij

pinctrl: sunxi: Fix gpio_set behaviour

2013-08-07T19:57:13Z

The current gpio_set function is ignoring the previous value set in the GPIO value register, which leads in erasing the values already set for the other GPIOs in the same bank when setting the value of a given GPIO. Add the usual read/mask/write pattern to fix this brown paper bag bug. Signed-off-by: Maxime Ripard Signed-off-by: Linus Walleij

pinctrl: sunxi: Read register before writing to it in irq_set_type

2013-08-07T18:39:25Z

The current irq_set_type code doesn't read the current register value before writing to it, leading to the older programmed values being overwritten and everything but the latest value being reset. Signed-off-by: Maxime Ripard Signed-off-by: Linus Walleij

pinctrl: fix a memleak when freeing maps

2013-07-25T15:18:36Z

We forgot to free the node itself when free:ing a map. Reported-by: xulinuxkernel Reviewed-by: Stephen Warren Signed-off-by: Linus Walleij

pinctrl: pinctrl-single: fix compile warning when no CONFIG_PM

2013-07-22T21:00:55Z

This warning has been introduced by the commit 0f9bc4bcdf4f pinctrl: single: adopt pinctrl sleep mode management Signed-off-by: Jean-Francois Moine Acked-by: Tony Lindgren Signed-off-by: Linus Walleij

pinctrl: sh-pfc: fix SDHI0 VccQ regulator on sh73a0 with DT

2013-07-22T19:09:03Z

The PFC pinctrl driver on sh73a0 is also regiatering a VccQ regulator for SDHI0. However, its consumers list only included the platform-data based SDHI device name. When booted with DT SDHI0 couldn't enable VccQ and therefore was unusable. Fix this by adding a consumer with DT-based name.

pinctrl: sirf: add usp0_uart_nostreamctrl pin group for usp-uart without flowctrl

2013-07-21T22:52:19Z

this patch adds the lost pin group which supports to let USP0 to simulate a UART without hardware flow control. Signed-off-by: Qipan Li Signed-off-by: Barry Song Signed-off-by: Linus Walleij

pinctrl: sirf: fix the pin number and mux bit for usp0

we missed a pin and related mux bit for usp pin group, this patch fixes it. Signed-off-by: Qipan Li Signed-off-by: Barry Song Signed-off-by: Linus Walleij

Pull pin control changes from Linus Walleij: - A large slew of improvements of the Genric pin configuration support, and deployment in four different platforms: Rockchip, Super-H PFC, ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing and debugfs support into shape. - We also have device tree support with generic naming conventions for the generic pin configuration. - Delete the unused and confusing direct pinconf API. Now state transitions is *the* way to control pins and multiplexing. - New drivers for Rockchip, TZ1090, and TZ1090 PDC. - Two pin control states related to power management are now handled in the device core: "sleep" and "idle", removing a lot of boilerplate code in drivers. We do not yet know if this is the final word for pin PM, but it already make things a lot easier to handle. - Handle sparse GPIO ranges passing a list of disparate pins, and utilize these in the new BayTrail (x86 Atom SoC) driver. - Make the sunxi (AllWinner) driver handle external interrupts. - Make it possible for pinctrl-single to handle the case where several pins are managed by a single register, and augment it to handle sleep modes. - Cleanups and improvements for the abx500 drivers. - Move Sirf pin control drivers to their own directory, support save/restore of context and add support for the SiRFatlas6 SoC. - PMU muxing for the Dove pinctrl driver. - Finalization and support for VF610 in the i.MX6 pinctrl driver. - Smoothen out various Exynos rough edges. - Generic cleanups of various kinds. * tag 'pinctrl-for-v3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (82 commits) pinctrl: vt8500: wmt: remove redundant dev_err call in wmt_pinctrl_probe() pinctrl: remove bindings for pinconf options needing more thought pinctrl: remove slew-rate parameter from tz1090 pinctrl: set unit for debounce time pinconfig to usec pinctrl: more clarifications for generic pull configs pinctrl: rip out the direct pinconf API pinctrl-tz1090-pdc: add TZ1090 PDC pinctrl driver pinctrl-tz1090: add TZ1090 pinctrl driver pinctrl: samsung: Staticize drvdata_list pinctrl: rockchip: Add missing irq_gc_unlock() call before return error pinctrl: abx500: rework error path pinctrl: abx500: suppress hardcoded value pinctrl: abx500: factorize code pinctrl: abx500: fix abx500_gpio_get() pinctrl: abx500: fix abx500_pin_config_set() pinctrl: abx500: Add device tree support sh-pfc: Guard DT parsing with #ifdef CONFIG_OF pinctrl: add Intel BayTrail GPIO/pinctrl support pinctrl: fix pinconf_ops::pin_config_dbg_parse_modify kerneldoc pinctrl: Staticize local symbols ...

Merge tag 'regmap-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

2013-07-03T18:40:58Z

Pull regmap updates from Mark Brown: "A small but useful set of regmap updates this time around: - An abstraction for bitfields within a register map contributed by Srinivas Kandagatla, allowing drivers to cope more easily when hardware designers randomly move things about (mainly when talking to things like system controllers). - Changes from Lars-Peter Clausen to allow the MMIO regmap to be used from hard IRQ context. - Small improvements to the cache infrastructure and performance, including a default cache sync operation so now all regmaps can sync easily. There's also a pinctrl driver making use of the new bitfield API, merged here for dependency reasons. There will be a simple add/add conflict with the pinctrl tree as a result." * tag 'regmap-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: pinctrl: st: Remove unnecessary use of of_match_ptr macro pinctrl: st: fix return value check pinctrl: st: Add pinctrl and pinconf support. regmap: debugfs: Suppress cache for partial register files regmap: Add regmap_field APIs regmap: core: Cache all registers by default when cache is enabled regmap: Implemented default cache sync operation regmap: Make regmap-mmio usable from atomic contexts regmap: regcache: Fixup locking for custom lock callbacks regmap: debugfs: Fix return from regmap_debugfs_get_dump_start regmap: debugfs: Don't mark lockdep as broken due to debugfs write regmap: rbtree: Use range information to allocate nodes regmap: rbtree: Factor out node allocation regmap: Make regmap_check_range_table() a public API regmap: Add support for discarding parts of the register cache
