arm: exynos: odroid: Fix build if BOARD_TYPES are not set

2019-03-11T06:53:50Z

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 Signed-off-by: Minkyu Kang

arm: exynos: Remove duplicated "boardname" env setting

2019-03-11T06:53:29Z

Various places in the code set "boardname" env property. It was used for booting from ITB images and choosing proper DTB file name. Instead of duplicating it, use existing U-Boot wide - "board_name". Signed-off-by: Krzysztof Kozlowski Reviewed-by: Lukasz Majewski Signed-off-by: Minkyu Kang

arm: exynos: arndale: Replace Chander Kashyap inactive maintainer

2019-03-11T06:53:29Z

Last activity from Arndale (Exynos5250) board maintainer Chander Kashyap was in January 2014 (Signed-off). Recently his samsung.com email bounces with 550 (5.1.1 Recipient address rejected: User unknown). Add Krzysztof Kozlowski as odd fixer for this board.

arm: exynos: Wait till ADC stabilizes before checking Odroid HC1 revision

2019-03-11T06:53:19Z

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). Signed-off-by: Krzysztof Kozlowski Tested-by: Anand Moon Signed-off-by: Minkyu Kang

arm: exynos: odroid-xu3: Display info late to have proper type

2019-03-11T06:53:19Z

Printing the "Type" of board requires proper detection of revision which can happen only late because regulators are needed. Signed-off-by: Krzysztof Kozlowski Tested-by: Anand Moon Signed-off-by: Minkyu Kang

arm: exynos: Detect revision later, when all resources are ready

2019-03-11T06:53:19Z

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.

samsung: mmc: Drop old MMC init code

2019-02-09T19:50:22Z

Now that these boards use driver model we can drop the old code. At present s5p_mmc_init() is still used by goni and smdkv310 so cannot be removed unless we remove those boards. Signed-off-by: Simon Glass Reviewed-by: Lukasz Majewski Reviewed-by: Minkyu Kang

samsung: Drop board_enable_audio_codec()

2019-02-09T19:50:22Z

This function is not needed now since the audio codecs have been converted to proper drivers. The codec-enable GPIO is handled there. Signed-off-by: Simon Glass Reviewed-by: Lukasz Majewski Reviewed-by: Minkyu Kang

At present the model is shown twice, once in the generic code and once in the exynos code. Drop the latter. Signed-off-by: Simon Glass Reviewed-by: Lukasz Majewski Reviewed-by: Minkyu Kang
