2024-09-26soc: ep93xx: drop reference to removed EP93XX_SOC_COMMON configLukas Bulwahn
Commit 6eab0ce6e1c6 ("soc: Add SoC driver for Cirrus ep93xx") adds the config EP93XX_SOC referring to the config EP93XX_SOC_COMMON. Within the same patch series of the commit above, the commit 046322f1e1d9 ("ARM: ep93xx: DT for the Cirrus ep93xx SoC platforms") then removes the config EP93XX_SOC_COMMON. With that the reference to this config is obsolete. Simplify the expression in the EP93XX_SOC config definition.

2024-09-12clk: ep93xx: Fix off by one in ep93xx_div_recalc_rate()Dan Carpenter
The psc->div[] array has psc->num_div elements. These values come from when we call clk_hw_register_div(). It's adc_divisors and ARRAY_SIZE(adc_divisors)) and so on. So this condition needs to be >= instead of > to prevent an out of bounds read.

2024-09-12pinctrl: add a Cirrus ep93xx SoC pin controllerNikita Shubin
Add a pin control (only multiplexing) driver for ep93xx SoC so we can fully convert ep93xx to device tree. This driver is capable of muxing ep9301/ep9302/ep9307/ep9312/ep9315 variants, this is chosen based on "compatible" in device tree.

2024-09-12gpio: ep93xx: split device in multipleNikita Shubin
Prepare ep93xx SOC gpio to convert into device tree driver: - dropped banks and legacy defines - split AB IRQ and make it shared We are relying on IRQ number information A, B ports have single shared IRQ, while F port have dedicated IRQ for each line. Also we had to split single ep93xx platform_device into multiple, one for each port, without this we can't do a full working transition from legacy platform code into device tree capable. All GPIO_LOOKUP were change to match new chip namings.

2024-09-11ep93xx: clock: Fix off by one in ep93xx_div_recalc_rate()Dan Carpenter
The psc->div[] array has psc->num_div elements. These values come from when we call clk_hw_register_div(). It's adc_divisors and ARRAY_SIZE(adc_divisors)) and so on. So this condition needs to be >= instead of > to prevent an out of bounds read.
