treewide: Convert macro and uses of section(foo) to section("foo")

2021-05-24T18:21:30+00:00

This commit does the same thing as Linux commit 33def8498fdd.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

clk: Add support for the k210 clock driver pre-relocation

2021-05-14T08:20:48+00:00

Variables which had previously been stored in .bss are moved to .data. In
addition, probed needs to be reset when the clock driver is re-bound
post-relocation.

clk: k210: Move the clint clock to under aclk

2021-05-14T08:20:48+00:00

No other (real) clocks have the cpu clock as their parent; instead they are
children of aclk. Move the clint clock under aclk to match them.

clk: k210: Remove k210_register_pll

2021-05-14T08:20:48+00:00

This simplifies the PLL creation process, since we don't have to pass all
the parameters individually.

clk: k210: Fix PLL enable always getting taken

2021-05-14T08:20:47+00:00

This conditional always evaluated as false, regardless of the value of reg.
Fix it so that it properly tests the bits in the PLL register. Also test
PLL_EN, now that we set it.

clk: k210: Fix PLLs not being enabled

2021-05-14T08:20:47+00:00

After starting or setting the rate of a PLL, the enable bit must be set.

This fixes a bug where the AI ram would not be accessible, because it
requires PLL1 to be running.

clk: Update drivers to use -EINVAL

2021-04-06T04:33:19+00:00

At present some drivers use -ENOSUPP to indicate that an unknown or
unsupported clock is used. Most use -EINVAL, indicating an invalid value,
so convert everything to that.

clk: kendryte: no need to check argument of free()

2020-10-26T01:27:13+00:00

free() checks if its argument is NULL. No need to check it twice.

riscv: clk: Add CLINT clock to kendryte clock driver

2020-09-30T00:54:46+00:00

Another "virtual" clock (in the sense that it isn't configurable). This
could possibly be done as a clock in the device tree, but I think this is a
bit cleaner.

clk: Drop dm.h header file in clk-provider.h

2020-08-04T02:19:54+00:00

This header file should not be included in other header files. Remove it
and use a forward declaration and un-inlining of dev_get_clk_ptr()
instead.

Fix up the kendryte header files to avoid build errors.
