arm: Remove mx35pdk board

2021-02-15T15:11:38Z

This board has not been converted to CONFIG_DM_MMC by the deadline of v2019.04, which is almost two years ago. In addition there are other DM migrations it is also missing. Remove it. Cc: Stefano Babic Signed-off-by: Tom Rini Acked-by: Stefano Babic

serial: sifive: Cast dev_read_addr() with uintptr_t

2021-02-03T10:38:41Z

dev_read_addr() returns fdt_addr_t which is now a 64-bit address. In a 32-bit build, this causes the following warning seen when building serial_sifive.c: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] Cast the return value with uintptr_t. Signed-off-by: Bin Meng

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42Z

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

serial: a3720: Implement pending method for output direction

2021-01-27T12:12:51Z

To check if some output characters are waiting either in Transmitter Holding Register or Transmitter Shift Register we need to look at TX_EMPTY bit of UART Status Register. Signed-off-by: Pali Rohár Reviewed-by: Stefan Roese

serial: add uart driver for MediaTek MT7620 SoC

2021-01-24T20:39:26Z

This patch adds uart support for MediaTek MT7620 and earlier SoCs. The UART used by MT7620 is incompatible with the ns16550a driver. All registers of this UART have different addresses. A special 16-bit register for Divisor Latch is used to set the baudrate instead of the original two 8-bit registers (DLL and DLM). The driver supports of-platdata which is useful for tiny SPL.

drivers: serial: probe all uart devices

2021-01-16T19:49:09Z

U-Boot DM model probe only single device at a time which is enabled and configured using device tree or platform data method. PL011 UART IP is SBSA compliant and firmware does the serial port set-up, initialization and let the kernel use UART port for sending and receiving characters. Normally software talk to one serial port time but some LayerScape platform require all the UART devices enabled in Linux for various use case. Adding support to probe all enabled serial devices like SBSA compliant PL011 UART ports probe and initialization by firmware.
