Douglas Anderson [Thu, 6 Sep 2018 22:49:06 +0000 (15:49 -0700)]
soc: qcom: geni: geni_se_clk_freq_match() should always accept multiples

The geni_se_clk_freq_match() has some strange semantics.  Specifically
it is defined with two modes:
1. It can find a clock that's an exact multiple of the requested rate
2. It can find a non-exact match but it can't handle multiples then

...but callers should always be able to handle a clock that is a
multiple of the requested clock so mode #2 doesn't really make sense.
Let's change the semantics so that the non-exact match can also accept
multiples and then change the code to handle that.

The only caller of this code is the unlanded SPI driver [1] which
currently passes "exact = True", thus it should be safe to change the
semantics in this way.  ...and, in fact, the SPI driver should likely
be modified to pass "exact = False" (with the new semantics) since
that will allow it to work with SPI devices that request a clock rate
that doesn't exactly match a rate we can make.

soc: qcom: geni: Don't ignore clk_round_rate() errors in geni_se_clk_tbl_get()

The function clk_round_rate() is defined to return a "long", not an
"unsigned long".  That's because it might return a negative error
code.  Change the call in geni_se_clk_tbl_get() to check for errors.

While we're at it, get rid of a useless init of "freq".

NOTE: overall the idea that we should iterate over clk_round_rate() to
try to reconstruct a table already present in the clock driver is
questionable.  Specifically:
- This method relies on "clk_round_rate()" rounding up.
- This method only works if the table is sorted and has no duplicates.
...this patch doesn't try to fix those problems, it just makes the
error handling more correct.

Let's change this to be more explicit. Introduce three macros for the

firmware: qcom: scm: Refactor clock handling

At one point in time all "future" platforms required three clocks, so
the binding and driver was written to treat this as the default case.
But new platforms has no clock requirements, which currently makes them
all a special case, causing the need for a patch in the binding and
driver for each new platform added.

This patch reworks the driver logic so that it will attempt to acquire
all three clocks and fail based on the given compatible. This allow us
to drop the clock requirement from "qcom,scm", in a way that will remain
backwards compatible with existing DT files.

Specific compatibles are added for apq8084, msm8916 and msm8974 to match
the updated binding and although equivalent to qcom,scm both ipq4019 and
msm8996 are kept as these have been used without fallback to qcom,scm.

The result of this patch is that new platforms, that require no clocks,
can be use the fallback compatible of "qcom,scm".

soc: qcom: geni: geni_se_clk_freq_match() should always accept multiples

The geni_se_clk_freq_match() has some strange semantics.  Specifically
it is defined with two modes:
1. It can find a clock that's an exact multiple of the requested rate
2. It can find a non-exact match but it can't handle multiples then

...but callers should always be able to handle a clock that is a
multiple of the requested clock so mode #2 doesn't really make sense.
Let's change the semantics so that the non-exact match can also accept
multiples and then change the code to handle that.

The only caller of this code is the unlanded SPI driver [1] which
currently passes "exact = True", thus it should be safe to change the
semantics in this way.  ...and, in fact, the SPI driver should likely
be modified to pass "exact = False" (with the new semantics) since
that will allow it to work with SPI devices that request a clock rate
that doesn't exactly match a rate we can make.

5 years agosoc: qcom: geni: Don't ignore clk_round_rate() errors in geni_se_clk_tbl_get()

soc: qcom: geni: Don't ignore clk_round_rate() errors in geni_se_clk_tbl_get()

The function clk_round_rate() is defined to return a "long", not an
"unsigned long".  That's because it might return a negative error
code.  Change the call in geni_se_clk_tbl_get() to check for errors.

While we're at it, get rid of a useless init of "freq".

NOTE: overall the idea that we should iterate over clk_round_rate() to
try to reconstruct a table already present in the clock driver is
questionable.  Specifically:
- This method relies on "clk_round_rate()" rounding up.
- This method only works if the table is sorted and has no duplicates.
...this patch doesn't try to fix those problems, it just makes the
error handling more correct.

soc: qcom: geni: Make version macros simpler

This macro doesn't work, because it hides a local variable inside of the
macro to hold the version and that variable name is called 'ver' and
'version' sometimes.

Let's change this to be more explicit. Introduce three macros for the
major, minor, and step of the version, and require callers to pass the
version in to get the part of the version out. This way we don't hide
local variables inside macros and things are less evil overall.
