dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25+00:00

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass

treewide: convert devfdt_get_addr() to dev_read_addr()

2020-07-25T20:46:57+00:00

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

serial: uniphier: enable FIFO

2020-07-11T12:30:21+00:00

This UART controller is integrated with a FIFO. Enable it. You can put the next character into the FIFO while the transmitter is sending out the current character. This works slightly faster. Signed-off-by: Masahiro Yamada

serial: uniphier: flush transmitter before changing hardware settings

2020-07-11T12:30:21+00:00

Ensure the transmitter is empty when chaining the baudrate or any hardware settings. If a character is remaining in the transmitter, the console will be garbled. Signed-off-by: Masahiro Yamada

serial: uniphier: use register macros instead of structure

2020-07-11T12:30:21+00:00

After all, I am not a big fan of using a structure to represent the hardware register map. You do not need to know the entire register map. Add only necessary register macros. Use FIELD_PREP() instead of maintaining a pair of shift and mask. Signed-off-by: Masahiro Yamada

serial: uniphier: set clock rate without clock-frequency property

2018-06-22T16:28:15+00:00

In Linux, the clock rate of the UART is given by the clock driver. If you try to follow that in U-Boot, you would end up with adding more u-boot,dm-pre-reloc properties, and also the clock driver would be too big for SPL, which is used for UniPhier ARMv7 platform. The current solution is to add 'clock-frequency' property to the UART nodes, but it does not exist in the DT files in Linux. I do not want to let DT diverge for U-Boot. Check the SoC compatible and set the clock rate according to it. This will be helpful to sync DT between Linux and U-Boot. Signed-off-by: Masahiro Yamada
