2019-03-11arm: exynos: odroid: Fix build if BOARD_TYPES are not setKrzysztof Kozlowski
CONFIG_BOARD_TYPES is necessary for Odroid X/X2/U3 boards to detect proper revision. However building should succeed even without it. While moving code around, document also the reference clock selection. This fixes the build error without CONFIG_BOARD_TYPES: board/samsung/odroid/odroid.c: In function 'board_usb_init': board/samsung/odroid/odroid.c:473:8: error: 'gd_t' {aka 'volatile struct global_data'} has no member named 'board_type' if (gd->board_type == ODROID_TYPE_U3) ^~ Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

2019-03-11arm: dts: exynos: Add ramp delay property to LDO regulators to Odroid XU3 familyKrzysztof Kozlowski
Add startup time to LDO regulators of S2MPS11 PMIC on Odroid XU3/XU4/HC1 family of boards to be sure the voltage is proper before relying on the regulator. The datasheet for all the S2MPS1x family is inconsistent here and does not specify unambiguously the value of ramp delay for LDO. It mentions 30 mV/us in one timing diagram but then omits it completely in LDO regulator characteristics table (it is specified for bucks). However the vendor kernels for Galaxy S5 and Odroid XU3 use values of 12 mV/us or 24 mV/us. Without the ramp delay value the consumers do not wait for voltage settle after changing it. Although the proper value of ramp delay for LDOs is unknown, it seems safer to use at least some value from reference kernel than to leave it unset.

Fix detection of Odroid HC1 (Exynos5422) after reboot if kernel disabled the LDO4/VDD_ADC regulator. The LDO4 supplies both ADC block and the ADC input AIN9. Voltage on AIN9 will rise slowly, so use delay of 5 milliseconds instead of timers-based loop to wait for voltage stabilization. First reads on Odroid HC1 return 305, 1207, 1297 and finally 1308 (reference value is 1309).

2019-03-11arm: exynos: Detect revision later, when all resources are readyKrzysztof Kozlowski
Detection of board revision is done early - before power setup. In case of Odroid XU3/XU4/HC1 family, the detection is done using ADC which is supplied by LDO4/VDD_ADC regulator. This regulator could be turned off (e.g. by kernel before reboot). If ADC is used early, the regulators are not yet available and the detection won't work. Split the revision detection out of set_board_type() into separate function called later - either when displaying board info (in late mode) or during misc_init_r. The idea is that set_board_type() will be called early so its method of detection are limited to flattened device tree (exynos5-dt-types.c for Exynos5) or GPIO (odroid.c for Exynos4412). The newly added set_board_revision() can be called only later, when resources like regulator are available. This is necessary to fix the detection of Odroid HC1 after reboot, if kernel turned off the LDO4 regulator.

With current order of include files, the file designware_spi.c can't see that the struct global_data has the member board_type when CONFIG_BOARD_TYPES is defined. By not seeing this then all the members are shifted in the struct global_data. So when the driver is trying to read from device tree blob, it would pass the wrong address to the function 'fdtdev_get_int'. This will make to use the default frequency 500000.
