pinctrl: renesas: Fix fall-through warnings for Clang

2020-11-23T08:47:28Z

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning by explicitly adding a break statement instead of letting the code fall through to the next case.

pinctrl: renesas: Constify sh73a0_vccq_mc0_ops

2020-11-13T14:37:41Z

The only usage of sh73a0_vccq_mc0_ops is to assign its address to the ops field in the regulator_desc struct, which is a const pointer. Make it const to allow the compiler to put it in read-only memory.

pinctrl: renesas: Protect GPIO leftovers by CONFIG_PINCTRL_SH_FUNC_GPIO

2020-11-13T14:37:41Z

On SuperH and ARM SH/R-Mobile SoCs, the pin control driver handles GPIOs, too. To reduce code size when compiling a kernel supporting only modern SoCs, most, but not all, of the GPIO functionality is protected by checks for CONFIG_PINCTRL_SH_FUNC_GPIO. Factor out the remaining parts when not needed: 1. sh_pfc_soc_info.{in,out}put describe GPIO pins that have input resp. output capabilities (SuperH and SH/R-Mobile). 2. sh_pfc_soc_info.gpio_irq{,_size} describe the mapping from GPIO pins to interrupt numbers (SH/R-Mobile). 3. sh_pfc_gpio_set_direction() configures GPIO direction, called from the GPIO driver through pinctrl_gpio_direction_{in,out}put() (SH/R-Mobile). Unfortunately this function cannot just be moved to drivers/pinctrl/renesas/gpio.c, as it relies on knowledge of sh_pfc_pinctrl, which is internal to drivers/pinctrl/renesas/pinctrl.c. While code size reduction is minimal, this does help in documenting depencies. Signed-off-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/20201028151637.1734130-9-geert+renesas@glider.be

pinctrl: renesas: r8a7778: Use common R-Car bias handling

2020-11-13T14:37:41Z

Currently, the rcar_pinmux_[gs]et_bias() helpers handle only SoCs that have separate LSI Pin Pull-Enable (PUEN) and Pull-Up/Down Control (PUD) registers, like R-Car Gen3 and RZ/G2. Update the function to handle SoCs that have only LSI Pin Pull-Up Control Register (PUPR), like R-Car Gen1/Gen2 and RZ/G1. Reduce code duplication by converting the R-Car M1A pin control driver to use the common handler. Note that this changes behavior in case the (invalid!) option "bias-pull-down" is used in an R-Car M1A DTS: before, it was ignored silently; after this change, it is considered the same as "bias-pull-up".

pinctrl: renesas: r8a7778: Use physical addresses for PUPR regs

2020-11-13T14:37:41Z

The handling of the LSI Pin Pull-Up Control Registers (PUPR) on R-Car M1A uses register offsets instead of register physical addresses. This is different from the handling on other R-Car parts. Convert the bias handling from register offsets to physical addresses. This increases uniformity, and prepares for consolidation of the bias handling.

pinctrl: renesas: Factor out common R-Car Gen3 bias handling

2020-11-13T14:37:41Z

All pin control drivers for R-Car Gen3 SoCs contain identical bias handling. Reduce code duplication by moving it to the common pinctrl.c code. Signed-off-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/20201028151637.1734130-6-geert+renesas@glider.be
