Przemyslaw Marczak 1611c8cbcf exynos5-dt-types: add board detection for Odroid XU3/XU3L/XU4. ... 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>		2015-11-02 10:38:00 +09:00
