module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself. Scripted using git grep -l -e MODULE_IMPORT_NS -e EXPORT_SYMBOL_NS | while read file; do awk -i inplace ' /^#define EXPORT_SYMBOL_NS/ { gsub(/__stringify$ns$/, "ns"); print; next; } /^#define MODULE_IMPORT_NS/ { gsub(/__stringify$ns$/, "ns"); print; next; } /MODULE_IMPORT_NS/ { $0 = gensub(/MODULE_IMPORT_NS$([^)]*)$/, "MODULE_IMPORT_NS(\"\\1\")", "g"); } /EXPORT_SYMBOL_NS/ { if ($0 ~ /(EXPORT_SYMBOL_NS[^(]*)$([^,]+),/) { if ($0 !~ /(EXPORT_SYMBOL_NS[^(]*)\(([^,]+), ([^)]+)$/ && $0 !~ /(EXPORT_SYMBOL_NS[^(]*)/ && $0 !~ /^my/) { getline line; gsub(/[[:space:]]*\\$/, ""); gsub(/[[:space:]]/, "", line); $0 = $0 " " line; } $0 = gensub(/(EXPORT_SYMBOL_NS[^(]*)$([^,]+), ([^)]+)$/, "\\1(\\2, \"\\3\")", "g"); } } { print }' $file; done Requested-by: Masahiro Yamada Signed-off-by: Peter Zijlstra (Intel) Link: https://mail.google.com/mail/u/2/#inbox/FMfcgzQXKWgMmjdFwwdsfgxzKpVHWPlc Acked-by: Greg KH Signed-off-by: Linus Torvalds

pinctrl: merrifield: Replace kernel.h by what is actually being used

2023-10-03T13:29:31Z

The kernel.h is a mess of unrelated things and we only used it as a proxy to array_size.h, hence switch from former to the latter. Signed-off-by: Andy Shevchenko

pinctrl: merrifield: Adapt to Intel Tangier driver

2023-08-15T14:31:50Z

Make use of Intel Tangier as a library driver for Merrifield. Signed-off-by: Raag Jadav Link: https://lore.kernel.org/r/20230814054033.12004-3-raag.jadav@intel.com Signed-off-by: Andy Shevchenko

pinctrl: merrifield: Use BUFCFG_PINMODE_GPIO in ->pin_dbg_show()

2023-06-06T13:07:33Z

Use explicit comparison to BUFCFG_PINMODE_GPIO instead of implying it. Acked-by: Mika Westerberg Signed-off-by: Andy Shevchenko

pinctrl: merrifield: Fix open-drain pin mode configuration

2023-06-06T13:07:33Z

Currently the pin may not be configured as open-drain in some cases because the argument may be 0 for the boolean types of the pin configurations. Fix this by ignoring the argument. With that, allow to actually restore pin to the push-pull mode. Acked-by: Mika Westerberg Signed-off-by: Andy Shevchenko

pinctrl: merrifield: Convert to use new memeber in struct intel_function

2022-12-30T08:22:53Z

Convert driver to use generic data type and hence a new member in the struct intel_function. No functional change intended. Signed-off-by: Andy Shevchenko Acked-by: Mika Westerberg

pinctrl: merrifield: Use temporary variable for struct device

2022-11-03T11:43:22Z

Use temporary variable for struct device to make code neater. Signed-off-by: Andy Shevchenko Reviewed-by: Mika Westerberg

pinctrl: merrifield: Add missing header(s)

2022-10-24T14:06:47Z

Do not imply that some of the generic headers may be always included. Instead, include explicitly what we are direct user of. While at it, sort headers alphabetically. Signed-off-by: Andy Shevchenko Reviewed-by: Mika Westerberg

pinctrl: merrifield: Switch to to embedded struct pingroup

2022-06-20T11:38:29Z

Since struct intel_pingroup got a new member, switch the driver to use it. Signed-off-by: Andy Shevchenko Acked-by: Mika Westerberg

pinctrl: merrifield: Set default bias in case no particular value given

2020-11-16T10:07:57Z

When GPIO library asks pin control to set the bias, it doesn't pass any value of it and argument is considered boolean (and this is true for ACPI GpioIo() / GpioInt() resources, by the way). Thus, individual drivers must behave well, when they got the resistance value of 1 Ohm, i.e. transforming it to sane default. In case of Intel Merrifield pin control hardware the 20 kOhm sounds plausible because it gives a good trade off between weakness and minimization of leakage current (will be only 50 uA with the above choice).
