pinctrl: cherryview: Add a quirk to make Acer Chromebook keyboard work again

2017-04-11T08:09:39Z

After commit 47c950d10202 ("pinctrl: cherryview: Do not add all southwest and north GPIOs to IRQ domain") the driver does not add all GPIOs to the irqdomain. The reason for that is that those GPIOs cannot generate IRQs at all, only GPEs (General Purpose Events). This causes Linux virtual IRQ numbering to change. However, it seems some CYAN Chromebooks, including Acer Chromebook hardcodes these Linux IRQ numbers in the ACPI tables of the machine. Since the numbering is different now, the IRQ meant for keyboard does not match the Linux virtual IRQ number anymore making the keyboard non-functional. Work this around by adding special quirk just for these machines where we add back all GPIOs to the irqdomain. Rest of the Cherryview/Braswell based machines will not be affected by the change.

pinctrl: samsung: Add missing part for PINCFG_TYPE_DRV of Exynos5433

2017-04-10T07:34:08Z

The commit 1259feddd0f8("pinctrl: samsung: Fix the width of PINCFG_TYPE_DRV bitfields for Exynos5433") already fixed the different width of PINCFG_TYPE_DRV from previous Exynos SoC. However wrong merge conflict resolution was chosen in commit 7f36f5d11cda ("Merge tag 'v4.10-rc6' into devel") effectively dropping the changes for PINCFG_TYPE_DRV. Re-do them here. The macro EXYNOS_PIN_BANK_EINTW is no longer used so remove it.

pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()

2017-04-06T23:08:08Z

Recent pinctrl changes to allow dynamic allocation of pins exposed one more issue with the pinctrl pins claimed early by the controller itself. This caused a regression for IMX6 pinctrl hogs. Before enabling the pin controller driver we need to wait until it has been properly initialized, then claim the hogs, and only then enable it. To fix the regression, split the code into pinctrl_claim_hogs() and pinctrl_enable(). And then let's require that pinctrl_enable() is always called by the pin controller driver when ready after calling pinctrl_register_and_init().

pinctrl: st: add irq_request/release_resources callbacks

2017-03-23T09:10:39Z

When using GPIO as IRQ source, the GPIO must be configured in INPUT. Callbacks dedicated for this was missing in pinctrl-st driver. This fix the following kernel error when trying to lock a gpio as IRQ: [ 7.521095] gpio gpiochip7: (PIO11): gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ [ 7.526018] gpio gpiochip7: (PIO11): unable to lock HW IRQ 6 for IRQ [ 7.529405] genirq: Failed to request resources for 0-0053 (irq 81) on irqchip GPIO Signed-off-by: Patrice Chotard Signed-off-by: Linus Walleij

pinctrl: qcom: Don't clear status bit on irq_unmask

Clearing the status bit on irq_unmask will discard any pending interrupt that did arrive after the irq_ack, i.e. while the IRQ handler function was executing.

pinctrl: samsung: Fix memory mapping code

2017-03-23T09:10:38Z

Some pinctrls share memory regions, and devm_ioremap_resource does not allow to share resources, in opposition to devm_ioremap. This patch restores back usage of devm_ioremap function, but with proper error handling and logging.
