treewide: convert devfdt_get_addr_ptr() to dev_read_addr_ptr()

2020-08-22T14:53:37Z

When you enable CONFIG_OF_LIVE, you will end up with a lot of conversions. To help this tedious work, this commit converts devfdt_get_addr_ptr() to dev_read_addr_ptr() by coccinelle. I also removed redundant casts because dev_read_addr_ptr() returns an opaque pointer. To generate this commit, I ran the following semantic patch excluding include/dm/. @@ type T; expression dev; @@ -(T *)devfdt_get_addr_ptr(dev) +dev_read_addr_ptr(dev) @@ expression dev; @@ -devfdt_get_addr_ptr(dev) +dev_read_addr_ptr(dev) Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass

dm: core: Fix devfdt_get_addr_ptr return value

2020-08-22T13:59:14Z

According to the description of devfdt_get_addr_ptr, this function should return NULL on failure, but currently it returns (void *)FDT_ADDR_T_NONE. Fix this by making devfdt_get_addr_ptr return NULL on failure, as described in the function comments. Also, update the drivers currently checking (void *)FDT_ADDR_T_NONE to check for NULL.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46Z

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. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

aspeed: ast2500: Read clock ofdata in the correct method

2020-01-07T23:02:38Z

At present the clock driver reads its ofdata in the probe() method. This is not correct although it is often harmless. However in this case it causes a problem, something like this: - ast_get_scu() is called (from somewhere) to get the SCI address - this probes the clock - first sets up ofdata (which does nothing at present) - DM marks clock device as active - DM calls pinctrl - pinctrl probes and calls ast_get_scu() in ast2500_pinctrl_probe() - ast_get_scu() probes the clock, but sees it already marked as probed - ast_get_scu() accesses the clock's private data, with scu as NULL - DM calls clock probe function ast2500_clk_probe() which reads scu By putting the read of scu into the correct method, scu is read as part of ofdata setup, and everything is OK. Note: This problem did not matter until now since DM always probed all parents before reading a child's ofdata. The fact that pinctrl is a child of clock seems to trigger this strange bug.

aspeed: ast2500: fix D2-PLL clock setting in RGMII mode

2018-11-05T16:41:58Z

The algorithm in the ast2500_calc_clock_config() routine suffers from integer rounding and the requested rate does not get the appropriate set of Numerator, Denumerator, Post Divider parameters. This is the case for the D2-PLL clock used by the MAC controllers in RGMII mode. The requested rated is 250MHz but a 251MHz is assigned. The easiest way to fix this problem is to introduce an array of clock settings defining the N, M, P parameters for well known frequencies used by the Aspeed SoC.
