i2c: avoid dynamic stack use in dm_i2c_write

2022-07-19T11:46:28Z

The size of the dynamic stack allocation here is bounded by the if() statement. However, just allocating the maximum size up-front and doing malloc() if necessary avoids code duplication (the i2c_setup_offset() until the invocation of ->xfer), and generates much better (smaller) code: bloat-o-meter drivers/i2c/i2c-uclass.o.{0,1} add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-144 (-144) Function old new delta dm_i2c_write 552 408 -144 Total: Before=3828, After=3684, chg -3.76% It also makes static analysis of maximum stack usage (using the .su files that are automatically generated during build) easier if there are no lines saying "dynamic". [This is not entirely equivalent to the existing code; this now uses the stack for len <= 64 rather than len <= 63, but that seems like a more natural limit.] Signed-off-by: Rasmus Villemoes Reviewed-by: Heiko Schocher

i2c: ast_i2c: Remove SCL direct drive mode

2022-07-19T11:46:28Z

SCL direct drive mode prevents communication with devices that do clock stretching, so disable. The Linux driver doesn't use this mode, and the engine can handle clock stretching. Signed-off-by: Eddie James Reviewed-by: Heiko Schocher Reviewed-by: Joel Stanley Reviewed-by: ryan_chen

spl: Ensure all SPL symbols in Kconfig have some SPL dependency

2022-07-07T13:29:08Z

Tighten up symbol dependencies in a number of places. Ensure that a SPL specific option has at least a direct dependency on SPL. In places where it's clear that we depend on something more specific, use that dependency instead. This means in a very small number of places we can drop redundant dependencies.

The reset control was written for the ast2500 and directly programs the clocking register. So we can share the code with other SoC generations use the reset device to deassert the I2C reset line. Signed-off-by: Joel Stanley Reviewed-by: Ryan Chen

arm: samsung: Migrate a number of symbols to Kconfig

2022-06-28T21:04:37Z

- In a number of cases, use CONFIG_ARCH_EXYNOS[45] rather than CONFIG_EXYNOS[45] - In other cases, test for CONFIG_ARCH_EXYNOS or CONFIG_ARCH_S5PC1XX - Migrate specific SoC CONFIG values to Kconfig - Use CONFIG_TARGET_x rather than CONFIG_x - Migrate other CONFIG_EXYNOS_x symbols to Kconfig - Reference CONFIG_EXYNOS_RELOCATE_CODE_BASE directly as EXYNOS_RELOCATE_CODE_BASE - Rename CONFIG_S5P_PA_SYSRAM to CONFIG_SMP_PEN_ADDR to match the rest of U-Boot usage.
