2019-03-11arm: exynos: Detect revision later, when all resources are readyKrzysztof Kozlowski1-0/+1
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.

2018-10-23ARM: Samsung: Add Exynos5422-based Odroid HC2 supportDirk Meul1-0/+2
Odroid HC2 board is based on Odroid XU4 board, like the Odroid HC1. The linux kernel does not provide a hc2 DTB so the hc1 DTB is also used for the Odroid HC2. Resend because MUA changed whitespace.

2017-12-05ARM: Samsung: Add Exynos5422-based Odroid HC1 supportMarek Szyprowski1-0/+2
Odroid HC1 board is based on Odroid XU4 board, but it has no HDMI, no eMMC, no build-in USB3.0 hub, no extension port pins, and no GPIO button. USB3.0 ports are used for build-in JMicron USB to SATA bridge and Gigabit R8152 ethernet chips. HC1 uses only passive cooling. This patch also updates Odroid's ADCmax array and reduces ADC tolerance to 1% to ensure that XU4 and HC1 revisions are properly detected. I've tested this with XU3, XU3-lite, XU4 and HC1 boards. In case of my test boards I got following values from ADC register: 372, 370, 1281 and 1313.

2015-11-02exynos5-dt-types: add board detection for Odroid XU3/XU3L/XU4.Przemyslaw Marczak1-0/+27
This commit adds additional file with implementation of board detection code for Odroid-XU3/XU4. The detection depends on compatible found in fdt: - "samsung,exynos5" - uses Exynos5 generic code - "samsung,odroidxu3" - try detect XU3 revision There are few revisions of Odroid XU3/XU4, each can be detected by checking the value of channel 9 of built-in ADC: Rev ADC Board 0.1 0 XU3 0.1 0.2 372 XU3 0.2 | XU3L - no DISPLAYPORT 0.3 1280 XU4 0.1 The detection code depends on the ADC+10% value. Implementation of functions: - set_board_type() - read ADC and set type - get_board_rev() - returns board revision: 1..3 - get_board_type() - returns board type string Additional functions with return values of bool: - board_is_generic() - true if found compatible "samsung,exynos5" but not "samsung,odroidxu3" - board_is_odroidxu3() - true if found compatible "samsung,odroidxu3" and one of XU3 revision. - board_is_odroidxu4() - true if found compatible "samsung,odroidxu3" and XU4 revision. After I2C controller init, the get_board_type() can check if the XU3 board is a "Lite" variant, by probing chip 0x40 on I2C0 (INA231 - exists only on non-lite). This is useful for setting fdt file name at misc_init_r(). Enabled configs: - CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG - CONFIG_ODROID_REV_AIN - CONFIG_REVISION_TAG - CONFIG_BOARD_TYPES Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Minkyu Kang <mk7.kang@samsung.com> Cc: Simon Glass <sjg@chromium.org> Tested-by: Anand Moon <linux.amoon@gmail.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
2015-02-25dfu: samsung: move call to set_dfu_alt_info() to dfu common codePrzemyslaw Marczak1-3/+2
This common call can be used for setting proper entities based on dfu command arguments. The config: CONFIG_SET_DFU_ALT_INFO, was used only for few configs, and now it is common. The board file should implement: - set_dfu_alt_info() function Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [Test HW: Odroid U3 (Exynos 4412)]
2014-09-05samsung: board: enable support of multiple board typesPrzemyslaw Marczak1-0/+4
This change adds declaration of functions: - set_board_type() - called at board_early_init_f() - get_board_type() - called at checkboard() For supporting multiple board types in a one config - it is welcome to display the current board model. This is what get_board_type() should return. Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Minkyu Kang <mk7.kang@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

This change introduces new common function: - set_dfu_alt_info() - put dfu system and bootloader setting into $dfu_alt_info. functions declaration: - char *get_dfu_alt_system(void) - char *get_dfu_alt_boot(void) - void set_dfu_alt_info(void) and new config: - CONFIG_SET_DFU_ALT_INFO This function can be used for auto setting dfu configuration on boot. Such feature is useful for multi board support by one u-boot binary.
