stm32mp1: add support for LpDDR3

2019-09-02T15:52:29Z

This change enables LpDDR3 initialization with PMIC. Change-Id: I2409a808335dfacd69a8517cb8510cee98bb8161 Signed-off-by: Yann Gautier

stm32mp1: update clock driver

2019-02-14T10:20:23Z

Remove useless private structure in function prototypes. Add a reference counter on clocks. Prepare for future secured/shared/non-secured clocks.

stm32mp1: use functions to retrieve some peripheral addresses

2019-02-14T10:20:23Z

PWR, RCC, DDRPHYC & DDRCTRL addresses can be retrieved from device tree. Platform asserts the value read from the DT are the SoC addresses. Change-Id: I43f0890b51918a30c87ac067d3780ab27a0f59de Signed-off-by: Yann Gautier Signed-off-by: Etienne Carriere Signed-off-by: Nicolas LE BAYON

stm32mp1: update I2C and PMIC drivers

2019-02-14T10:20:23Z

Regulator configuration at boot takes more information from DT. I2C configuration from DT is done in I2C driver. I2C driver manages more transfer modes. The min voltage of buck1 should also be increased to 1.2V, else the platform does not boot. Heavily modifies stm32_i2c.c since many functions move inside the source file to remove redundant declarations.

stm32mp1: use new functions to manage timeouts

2019-02-14T10:20:23Z

Remove the previously use function: get_timer, and use new functions timeout_init_us and timeout_elapsed. Change-Id: I4e95b123648bff7ca91e40462a2a3ae24cfe1697 Signed-off-by: Yann Gautier Signed-off-by: Etienne Carriere Signed-off-by: Nicolas LE BAYON

stm32mp1: remove some dependencies on clocks and reset in drivers

2019-02-14T10:20:23Z

Include all RCC, clocks and reset headers from stm32mp1_def.h which if exported to the firmware through platform_def.h. The same dependency removal is done in common code as well. Some useless includes are also removed in stm32_sdmmc2 driver. Change-Id: I731ea5775c3fdb7f7b0c388b93923ed5e84b8d3f Signed-off-by: Yann Gautier

stm32mp1: make functions and macros more common

2019-02-14T10:20:23Z

Mainly remove suffix 1 from prefix stm32mp1 in several macros and functions that can be used in drivers shared by different platforms. Change-Id: I2295c44f5b1edac7e80a93c0e8dfd671b36e88e7 Signed-off-by: Yann Gautier Signed-off-by: Etienne Carriere

drivers: st: update drivers code

2019-01-18T14:45:08Z

Reword some traces. Use uintptr_t where required. Reduce scope of variables. Improve io_stm32image algo. Complete some IP registers definitions. Add failure on supported DDR (stm32mp1_ddr_init()). Fix cache flush on cache disable (stm32mp1_ddr_setup).

stm32mp1: update device tree files

2019-01-18T14:45:08Z

The drivers are also updated to reflect the changes. Set RCC as non-secure. Change-Id: I568fa1f418355830ad1d4d1cdcdb910fb362231b Signed-off-by: Yann Gautier

stm32mp1: rename stpmu1 to stpmic1

2019-01-18T14:45:08Z

This is the correct name of the IP. Rename stm32mp1_pmic files to stm32mp_pmic. Change-Id: I238a7d1f9a1d099daf7788dc9ebbd3146ba2f15f Signed-off-by: Yann Gautier
