Macros can be confusing on their own; hiding commas make things worse.
This can sometimes be downright misleading. A "good" example would be
the code in soc/intel/xeon_sp/spr/chip.c:
CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev,
This appears as CHIP_NAME() being some struct when in fact these are
defining 2 separate members of the same struct.
It was decided to remove this macro altogether, as it does not do
anything special and incurs a maintenance burden.

In commit e59f18bf29a8 ("drivers/i2c: Add PI7C9X2G608GP PCIe switch
driver (pi608gp)"), there were some suggestions after it's been already
merged.
This patch addresses the points regarding the code style and comments.
BUG=none
TEST=Build OK, no behavioral changes in the pi608gp driver, console logs
without changes.

merged.
This patch addresses the points regarding the number types - fix of the
printk format strings, inclusion of 'stdint.h' and marking the set of
allowed values as constant.

This patch adds some of the variety of configuration options exported
by the Pericom Inc. PI7C9X2G608GP PCIe switch over its SMBus interface.
Currently implemented options are only used to adjust the switch
upstream port amplitude and de-emphasis levels in millivolts. Only
values specified in the switch datasheet (in tables 6-6 and 6-8) are
allowed.
Example of a devicetree.cb entry:
chip drivers/i2c/pi608gp
register "gen2_3p5_enable" = "true"
register "gen2_3p5_amp" = "AMP_LVL_MV(425)"
register "gen2_3p5_deemph" = \
"DEEMPH_LVL_MV(37, 5)"
device i2c 0x6f on
ops pi608gp_ops
end
end
Link to the datasheet:
https://web.archive.org/web/20210225074853/https://www.diodes.com/assets/Datasheets/PI7C9X2G608GP.pdf
BUG=none
TEST=Create devicetree.cb and Kconfig entries for this driver
in a mainboard containing the switch and verify, that the values read
out from the switch config space match the values programmed over the
SMBus.
