Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

pinctrl: exynos: Add pinctrl support for Exynos850

2024-01-24T02:23:20Z

Add pinctrl support for Exynos850 SoC. It was mostly extracted from corresponding Linux kernel code [1]. Power down modes and external interrupt data were removed while converting the code for U-Boot, but everything else was kept almost unchanged.

pinctrl: exynos: Convert to use livetree API for fdt access

2024-01-09T15:59:28Z

Use counterpart dev_read_* functions instead of fdt* ones. It fixes checkpatch warnings like this: WARNING: Use the livetree API (dev_read_...) #54: FILE: drivers/pinctrl/exynos/pinctrl-exynos.c:137: pinvals[idx] = fdtdec_get_int(fdt, node, and also makes it possible to avoid using the global data pointer in the driver.

pinctrl: exynos: Reduce variables scope

2024-01-09T15:59:28Z

Pull some variables declared in exynos_pinctrl_set_state() into its loop, to reduce their scope. Style commit, no functional change. Signed-off-by: Sam Protsenko Signed-off-by: Minkyu Kang

pinctrl: exynos: Refactor handling the pin related dt properties

2024-01-09T15:59:28Z

All pin related dt properties (pin-function, pin-pud and pin-drv) are handled in a very similar way. Get rid of that code duplication by extracting the corresponding data knowledge into an actual data structure (array), and then just iterating over it. No functional change, it's a refactoring commit. Signed-off-by: Sam Protsenko Signed-off-by: Minkyu Kang

pinctrl: exynos: Support different register types in pin banks

2024-01-09T15:59:28Z

Get rid of hard-coded register offsets and widths. Instead provide a way for pinctrl drivers to specify different pin bank register offsets and widths. This in turn makes it possible to add support for new SoCs that have registers with offset/width values different than generic ones already available in pinctrl-exynos driver. Offset constants (now unused in pinctrl-exynos.c) are moved to pinctrl-exynos7420 driver, which is the single user of those constants. The design of this patch follows Linux kernel pinctrl-exynos driver design, in terms of added data structures and types. This patch doesn't add support for any new SoCs and shouldn't introduce any functional changes. Signed-off-by: Sam Protsenko Signed-off-by: Minkyu Kang

pinctrl: exynos: Rework pin_to_bank_base() to obtain data by name

2024-01-09T15:59:28Z

Rework pin_to_bank_base() function to obtain bank data structure by bank name instead of getting bank base address by pin name, and rename it to get_bank() to reflect this change. This in turn leads to the extraction of parse_pin(), so the caller has to use it before calling get_bank(). No functional change. This is a refactoring commit which prepares pinctrl driver code for handling different sizes of register fields, which will be added next. Signed-off-by: Sam Protsenko Signed-off-by: Minkyu Kang

pinctrl: exynos: Extract pin parsing code into a separate function

2024-01-09T15:59:28Z

Next commits are going to re-design the pin_to_bank_base() function and its usage in a way that the pin parsing code will be called separately. Extract it into a separate function first, as a refactoring commit. No functional change. Signed-off-by: Sam Protsenko Signed-off-by: Minkyu Kang
