pinctrl: tegra: tegra194: drop unused pin groups

2022-05-04T21:40:05Z

The sdmmc1_hv_trim_pins, sdmmc3_hv_trim_pins and sys_reset_n_pins are not defined as pin groups: drivers/pinctrl/tegra/pinctrl-tegra194.c:1119:27: error: ‘sdmmc3_hv_trim_pins’ defined but not used [-Werror=unused-const-variable=] 1119 | static const unsigned int sdmmc3_hv_trim_pins[] = { Proper fix would be to define them, but this requires knowledge from datasheet. Removal should not cause any harm and at least it silences the warnings.

pinctrl: tegra194: remove duplicate initializer again

pinctrl: tegra: Use correct offset for pin group

2021-10-25T23:27:39Z

Function tegra_pinctrl_gpio_request_enable() and tegra_pinctrl_gpio_disable_free() uses pin offset instead of group offset, causing the driver to use wrong offset to enable gpio. Add a helper function tegra_pinctrl_get_group() to parse the pin group and determine correct offset.

Pull pin control updates from Linus Walleij: "This is the bulk of the pin control changes for the v5.9 kernel series: Core changes: - The GPIO patch "gpiolib: Introduce for_each_requested_gpio_in_range() macro" was put in an immutable branch and merged into the pinctrl tree as well. 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: tegra: pinctrl-tegra194: Do not initialise field twice

Both PIN_PINGROUP_ENTRY_Y() and DRV_PINGROUP_ENTRY_Y() macros are called for each of the 2 pin groups defined here, and both of them initialise 'drv_reg', causing the compiler to complain. Only initialise 'drv_reg' once.
