phy: intel: Fix for warnings due to EMMC clock 175Mhz change in FIP

2021-07-20T14:00:22+00:00

[ Upstream commit 2f2b73a29d2aabf5ad0150856c3e5cb6e04dcfc1 ]

Since the EMMC clock was changed from 200Mhz to 175Mhz in FIP,
there were some warnings introduced, as the frequency values
being checked was still wrt 200Mhz in code. Hence, the frequency
checks are now updated based on the current 175Mhz EMMC clock changed
in FIP.

phy: uniphier-pcie: Fix updating phy parameters

2021-07-14T15:07:42+00:00

[ Upstream commit 4a90bbb478dbf18ecdec9dcf8eb708e319d24264 ]

The current driver uses a value from register TEST_O as the original
value for register TEST_I, though, the value is overwritten by "param",
so there is a bug that the original value isn't no longer used.

The value of TEST_O[7:0] should be masked with "mask", replaced with
"param", and placed in the bitfield TESTI_DAT_MASK as new TEST_I value.

phy: ralink: phy-mt7621-pci: properly print pointer address

2021-07-14T15:07:26+00:00

[ Upstream commit 652a6a2e3824ce2ebf79a2d5326940d05c4db036 ]

The way of printing the pointer address for the 'port_base'
address got into compile warnings on some architectures
[-Wpointer-to-int-cast]. Instead of use '%08x' and cast
to an 'unsigned int' just make use of '%px' and avoid the
cast. To avoid not really needed driver verbosity on normal
behaviour change also from 'dev_info' to 'dev_dbg'.

phy: usb: Fix misuse of IS_ENABLED

2021-05-14T12:10:37+00:00

While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not
for other symbols such as __BIG_ENDIAN that is provided directly by
the compiler.

Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.
