This patchset tries to improve its support by overcoming some limitations in the current implementation First, the support for scan and check for valid driver/aliases is added in order to generate U_BOOT_DEVICE entries with valid driver names. Secondly, the way information about linked noded (phandle) is generated in C structs is improved in order to make it easier to get a device associated to its data. Lastly the the suport for the property cd-gpios is added, which is used to configure the card detection gpio on MMC is added. This implementation is based in discussion in [1] and [2] [1] https://patchwork.ozlabs.org/patch/1249198/ [2] https://patchwork.ozlabs.org/project/uboot/list/?series=167495&state=* Walter Lozano (6): dtoc: add support to scan drivers core: extend struct driver_info to point to device dtoc: extend dtoc to use struct driver_info when linking nodes dtoc: update tests to match new platdata dtoc: update dtb_platdata to support cd-gpios dtoc add test for cd-gpios drivers/clk/clk-uclass.c | 8 +- drivers/core/device.c | 25 ++- drivers/core/root.c | 6 +- drivers/misc/irq-uclass.c | 4 +- drivers/mmc/ftsdc010_mci.c | 2 +- drivers/mmc/rockchip_dw_mmc.c | 2 +- drivers/mmc/rockchip_sdhci.c | 2 +- drivers/ram/rockchip/sdram_rk3399.c | 2 +- drivers/spi/rk_spi.c | 2 +- include/clk.h | 2 +- include/dm/device-internal.h | 2 +- include/dm/device.h | 19 +++ include/dm/platdata.h | 6 + tools/dtoc/dtb_platdata.py | 83 +++++++-- tools/dtoc/dtoc_test_phandle_cd_gpios.dts | 42 +++++ tools/dtoc/test_dtoc.py | 197 +++++++++++++++++----- 16 files changed, 332 insertions(+), 72 deletions(-) create mode 100644 tools/dtoc/dtoc_test_phandle_cd_gpios.dts
