2018-12-07gpio: stm32f7: Add gpio bank holes managementPatrice Chotard
In some STM32 SoC packages, GPIO bank has not always 16 gpios. Several cases can occur, gpio hole can be located at the beginning, middle or end of the gpio bank or a combination of these 3 configurations. For that, gpio bindings offer the gpio-ranges DT property which described the gpio bank mapping. Signed-off-by: Patrice Chotard <patrice.chotard@st.com>
2018-11-20misc: Update read() and write() methods to return bytes xferedSimon Glass

2018-11-14arm: stm32mp: Remove DM_FLAG_PRE_RELOC flagBin Meng
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before relocation. However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Patrick Delaunay <patrick.delaunay@st.com>
