2021-02-15Merge branch '2021-02-02-drop-asm_global_data-when-unused'Tom Rini1-0/+1
- Merge the patch to take <asm/global_data.h> out of <common.h>
2021-02-03serial: sifive: Cast dev_read_addr() with uintptr_tBin Meng1-1/+1
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.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
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 <asm/global_data.h> at all, so remove that include.

2020-12-14dm: treewide: Rename ..._platdata variables to just ..._platSimon Glass1-8/+8
Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-14dm: treewide: Rename ofdata_to_platdata() to of_to_plat()Simon Glass1-2/+2
This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-14dm: treewide: Rename dev_get_platdata() to dev_get_plat()Simon Glass1-6/+6
Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-14dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass1-16/+16
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-1/+1
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 <sjg@chromium.org>

2020-02-06dm: core: Require users of devres to include the headerSimon Glass1-0/+1
At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

2019-08-15riscv : serial: use rx watermark to indicate rx data is presentSagar Shrikant Kadam1-16/+7
In y-modem transfer mode, tstc/getc fail to check if there is any data available / received in RX FIFO, and so y-modem transfer never succeeds. Using receive watermark bit within ip register fixes the issue. This patch is based on commit c7392b7bc4e1 ("Use the RX watermark interrupt pending bit for TSTC") available at[1] [1] https://github.com/sifive/HiFive_U-Boot/tree/regression Signed-off-by: Sagar Shrikant Kadam <sagar.kadam@sifive.com> Reviewed-by: Anup Patel <anup.patel@wdc.com> Tested-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Padmarao Begari <padmarao.begari@microchip.com> Tested-by: Padmarao Begari <padmarao.begari@microchip.com>
2019-05-08serial: sifive: Change include orderJagan Teki1-1/+1
Like clk_get_by_index, there is requirement for clk_get_by_index_nodev. In this case to make common code functionalities for dev and nodev, clk_get_by_index is trying to get the index of clock by passing ofnode instead of actual dev like current gpio uclass does. In these scenarios with current order of include files the serial_sifive driver is unable to find CONFIG_ENV_SIZE. In file included from arch/riscv/include/asm/u-boot.h:23:0, from include/dm/of.h:10, from include/dm/ofnode.h:12, from include/clk.h:11, from drivers/serial/serial_sifive.c:6: include/environment.h:145:19: error: 'CONFIG_ENV_SIZE' undeclared here (not in a function); did you mean 'CONFIG_CMD_XIMG'? #define ENV_SIZE (CONFIG_ENV_SIZE - ENV_HEADER_SIZE) So, fix consists of changing the order of include files in serial_sifive.c to include first common.h file.

2019-02-27drivers: serial_sifive: Skip baudrate config if no input clockAtish Patra1-16/+16
It is possible that input clock is not available because clk device was not available and 'clock-frequency' DT property is also not available. In this case, instead of failing we should just skip baudrate config by returning zero.
