drivers: serial: Make serial_initialize return int

2020-08-06T18:27:27Z

serial_initialize is called only during the common init sequence, after relocation (in common/board_r.c). Because it has a void return value, it has to wrapped in initr_serial. In order to be able to get rid of this indirection, make serial_initialize return int.

msm_serial: Read bit rate register value from DT

2020-07-29T12:43:40Z

IPQ40xx and currently supported Snapdragon boards don't use the same one so enable reading it from DT, if no DT property is found default value is the same as the previous define. Signed-off-by: Robert Marko Reviewed-By: Ramon Fried

serial: meson: handle RX errors

2020-07-27T14:35:56Z

This checks and handles RX errors on the Amlogic UART controller after experiencing errors on the Khadas VIM3 & VIM3L when UART AO A lines are not connected. When the RX line is not connected, the first byte is erroneous and breaks the U-Boot autoboot, breaking automatic boot. This checks and drops any erroneous RX byte on pending and getc callbacks to avoid returning true to pending when an error byte is in the FIFO.

treewide: convert devfdt_get_addr() to dev_read_addr()

2020-07-25T20:46:57Z

When you enable CONFIG_OF_LIVE, you will end up with a lot of conversions. To generate this commit, I used coccinelle excluding drivers/core/, include/dm/, and test/ The semantic patch that makes this change is as follows: @@ expression dev; @@ -devfdt_get_addr(dev) +dev_read_addr(dev) Signed-off-by: Masahiro Yamada

treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()

2020-07-25T20:46:57Z

Use the _ptr suffixed variant instead of casting. Also, convert it to dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE. One curious part is an error check like follows in drivers/watchdog/omap_wdt.c: priv->regs = (struct wd_timer *)devfdt_get_addr(dev); if (!priv->regs) return -EINVAL; devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error. So, this code does not catch any error in DT parsing. dev_read_addr_ptr() returns NULL on error, so this error check will work. I generated this commit by the following command: $ find . -name .git -prune -o -name '*.[ch]' -type f -print | \ xargs sed -i -e 's/([^*)]*\*)devfdt_get_addr(/dev_read_addr_ptr(/' I manually fixed drivers/usb/host/ehci-mx6.c Signed-off-by: Masahiro Yamada
