We see these changes also here. - Improved debug output for pins used as GPIO. New drivers: - Ocelot Sparx5 SoC driver. - Intel Emmitsburg SoC subdriver. - Intel Tiger Lake-H SoC subdriver. - Qualcomm PM660 SoC subdriver. - Renesas SH-PFC R8A774E1 subdriver. Driver improvements: - Linear improvement and cleanups of the Intel drivers for Cherryview, Lynxpoint, Baytrail etc. Improved locking among other things. - Renesas SH-PFC has added support for RPC pins, groups, and functions to r8a77970 and r8a77980. - The newere Freescale (now NXP) i.MX8 pin controllers have been modularized. This is driven by the Google Android GKI initiative I think. - Open drain support for pins on the Qualcomm IPQ4019. - The Ingenic driver can handle both edges IRQ detection. - A big slew of documentation fixes all over the place. - A few irqchip template conversions by yours truly. * tag 'pinctrl-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (107 commits) dt-bindings: pinctrl: add bindings for MediaTek MT6779 SoC pinctrl: stmfx: Use irqchip template pinctrl: amd: Use irqchip template pinctrl: mediatek: fix build for tristate changes pinctrl: samsung: Use bank name as irqchip name pinctrl: core: print gpio in pins debugfs file pinctrl: mediatek: add mt6779 eint support pinctrl: mediatek: add pinctrl support for MT6779 SoC pinctrl: mediatek: avoid virtual gpio trying to set reg pinctrl: mediatek: update pinmux definitions for mt6779 pinctrl: stm32: use the hwspin_lock_timeout_in_atomic() API pinctrl: mcp23s08: Use irqchip template pinctrl: sx150x: Use irqchip template dt-bindings: ingenic,pinctrl: Support pinmux/pinconf nodes pinctrl: intel: Add Intel Emmitsburg pin controller support pinctl: ti: iodelay: Replace HTTP links with HTTPS ones Revert "gpio: omap: handle pin config bias flags" pinctrl: single: Use fallthrough pseudo-keyword pinctrl: qcom: spmi-gpio: Use fallthrough pseudo-keyword pinctrl: baytrail: Use fallthrough pseudo-keyword ...

| | * pinctrl: baytrail: Fix pin being driven low for a while on gpiod_get(..., ↵Hans de Goede2020-06-221-14/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GPIOD_OUT_HIGH) The pins on the Bay Trail SoC have separate input-buffer and output-buffer enable bits and a read of the level bit of the value register will always return the value from the input-buffer. The BIOS of a device may configure a pin in output-only mode, only enabling the output buffer, and write 1 to the level bit to drive the pin high. This 1 written to the level bit will be stored inside the data-latch of the output buffer. But a subsequent read of the value register will return 0 for the level bit because the input-buffer is disabled. This causes a read-modify-write as done by byt_gpio_set_direction() to write 0 to the level bit, driving the pin low! Before this commit byt_gpio_direction_output() relied on pinctrl_gpio_direction_output() to set the direction, followed by a call to byt_gpio_set() to apply the selected value. This causes the pin to go low between the pinctrl_gpio_direction_output() and byt_gpio_set() calls. Change byt_gpio_direction_output() to directly make the register modifications itself instead. Replacing the 2 subsequent writes to the value register with a single write. Note that the pinctrl code does not keep track internally of the direction, so not going through pinctrl_gpio_direction_output() is not an issue. This issue was noticed on a Trekstor SurfTab Twin 10.1. When the panel is already on at boot (no external monitor connected), then the i915 driver does a gpiod_get(..., GPIOD_OUT_HIGH) for the panel-enable GPIO. The temporarily going low of that GPIO was causing the panel to reset itself after which it would not show an image until it was turned off and back on again (until a full modeset was done on it). This commit fixes this. This commit also updates the byt_gpio_direction_input() to use direct register accesses instead of going through pinctrl_gpio_direction_input(), to keep it consistent with byt_gpio_direction_output(). Note for backporting, this commit depends on: commit e2b74419e5cc ("pinctrl: baytrail: Replace WARN with dev_info_once when setting direct-irq pin to output") Cc: stable@vger.kernel.org Fixes: 86e3ef812fe3 ("pinctrl: baytrail: Update gpio chip operations") Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

| | * pinctrl: intel: Disable input and output buffer when switching to GPIOAndy Shevchenko2020-06-221-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible scenario that pin has been in different mode, while the respective GPIO register has a leftover output buffer enabled. In such case when we request GPIO it will switch to GPIO mode, and thus to output with unknown value, followed by switching to input mode. This can produce a glitch on the pin. Disable input and output buffer when switching to GPIO to avoid potential glitches.
