2021-03-15pinctrl: qcom: sc8180x: add ACPI probe supportShawn Guo2-3/+122
It adds ACPI probe support for pinctrl-sc8180x driver. We have one problem with ACPI table, i.e. GIO0 (TLMM) block has one single memory resource to cover 3 tiles defined by SC8180X. To follow the hardware layout of 3 tiles which is already supported DT probe, it adds one function to replace the original single memory resource with 3 named ones for tiles. With that, We can map memory for ACPI in the same way as DT.

2021-03-15pinctrl: core: Set ret to 0 when group is skippedMichal Simek1-0/+2
Static analyzer tool found that the ret variable is not initialized but code expects ret value >=0 when pinconf is skipped in the first pinmux loop. The same expectation is for pinmux in a pinconf loop. That's why initialize ret to 0 to avoid uninitialized ret value in first loop or reusing ret value from first loop in second.

2021-03-15pinctrl: core: Handling pinmux and pinconf separatelyMichal Simek1-1/+22
Right now the handling order depends on how entries are coming which is corresponding with order in DT. We have reached the case with DT overlays where conf and mux descriptions are exchanged which ends up in sequence that firmware has been asked to perform configuration before requesting the pin. The patch is enforcing the order that pin is requested all the time first followed by pin configuration. This change will ensure that firmware gets requests in the right order.

2021-03-10pinctrl: pinmux: Add pinmux-select debugfs fileDrew Fustini1-0/+102
Add "pinmux-select" to debugfs which will activate a pin function for a given pin group: echo "<group-name function-name>" > pinmux-select The write operation pinmux_select() handles this by checking that the names map to valid selectors and then calling ops->set_mux(). The existing "pinmux-functions" debugfs file lists the pin functions registered for the pin controller. For example: function: pinmux-uart0, groups = [ pinmux-uart0-pins ] function: pinmux-mmc0, groups = [ pinmux-mmc0-pins ] function: pinmux-mmc1, groups = [ pinmux-mmc1-pins ] function: pinmux-i2c0, groups = [ pinmux-i2c0-pins ] function: pinmux-i2c1, groups = [ pinmux-i2c1-pins ] function: pinmux-spi1, groups = [ pinmux-spi1-pins ] To activate function pinmux-i2c1 on group pinmux-i2c1-pins: echo "pinmux-i2c1-pins pinmux-i2c1" > pinmux-select Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Reviewed-by: Tony Lindgren <tony@atomide.com> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Tested-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Drew Fustini <drew@beagleboard.org> Link: https://lore.kernel.org/r/20210302053059.1049035-3-drew@beagleboard.org Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

SAMA7G5 supports slew rate configuration. Adapt the driver for this. For output switching frequencies lower than 50MHz the slew rate needs to be enabled. Since most of the pins on SAMA7G5 fall into this category enabled the slew rate by default.

2021-01-23pinctrl: samsung: use raw_spinlock for lockingChanho Park4-22/+22
This patch converts spin_[lock|unlock] functions of pin bank to raw_spinlock to support preempt-rt. This can avoid BUG() assertion when irqchip callbacks are triggerred. Spinlocks can be converted rt_mutex which is preemptible when we apply preempt-rt patches. According to "Documentation/driver-api/gpio/driver.rst", "Realtime considerations: a realtime compliant GPIO driver should not use spinlock_t or any sleepable APIs (like PM runtime) as part of its irqchip implementation. - spinlock_t should be replaced with raw_spinlock_t.[1] " Cc: Tomasz Figa <tomasz.figa@gmail.com> Cc: Krzysztof Kozlowski <krzk@kernel.org> Cc: Sylwester Nawrocki <s.nawrocki@samsung.com> Cc: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Chanho Park <chanho61.park@samsung.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20210121030009.25673-1-chanho61.park@samsung.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Change the lcd-24bit group so that it only selects the pins that aren't in the lcd-18bit and lcd-generic groups (which breaks Device Tree in theory, but there is none out there for any JZ4760 based board, yet).
