2020-01-15usb: musb: davinci: Convert to use GPIO descriptorLinus Walleij1-0/+12
The DaVinci MUSB glue contains an optional GPIO line to control VBUS power, convert this to use a GPIO descriptor and augment the EVM board file to provide this descriptor. I can't get this driver to compile properly and it depends on broken but when I didn get it to compile brokenly, it did at least not complain about THIS code being broken so I don't think I broke the driver any more than what it already is. I did away with the ifdefs that do not work with multiplatform anyway so the day someone decides to resurrect the code, the path to get it working should be easier as well since DaVinci is now multiplatform.

dm644x_init_devices() is unnecessarily implemented as a postcore_initcall(). This does not cause any issues now, but creates issues when converting to common clock framework where clocks themselves become platform devices and are initialized later. Because of this, device clock acquisition and runtime PM on that device fails. Move the call to .init_machine() callback along with rest of platform device's registration.

This moves the call of davinci_clk_init() from map_io to init_time for all boards. This is the proper place to init clocks. This is also done in preparation for moving to the common clock framework. dm646x is a special case because we need to handle different ref_clk rates depending on which board is being used. The clock init in this case is modified to set the rate before registering the clocks instead of using davinci_set_refclk_rate() to recalculate the entire clock tree after all of the clocks are registered. Also, the cpu_clks field is removed from struct davinci_soc_info since it is no longer needed. Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>

2016-02-17ARM: davinci: make I2C support optionalArnd Bergmann1-2/+6
The davinci platform has tried to get support for the EEPROM right, but failed to get a clean build so far. At the moment, we get a warning whenever CONFIG_SYSFS is disabled, as that is needed by EEPROM_AT24: warning: (MACH_DAVINCI_EVM && MACH_SFFSDR && MACH_DAVINCI_DM6467_EVM && MACH_DAVINCI_DM365_EVM && MACH_DAVINCI_DA830_EVM && MACH_MITYOMAPL138 && MACH_MINI2440) selects EEPROM_AT24 which has unmet direct dependencies (I2C && SYSFS) Kevin Hilman initially added the 'select' to ensure that EEPROM_AT24 is always enabled in machines that really want it for normal operation (i.e. for reading the MAC address). This broke when I2C was disabled, and Russell King followed up with another patch to select that as well. I now see that the SYSFS dependency is still missing, which leaves us with three options: a) add 'select SYSFS' in addition to the others b) change AT24_EEPPROM to work without sysfs (should be possible) c) remove all those selects again and get the files to build when I2C is disabled. I would really hate to do a) because adding select statements that hardwire user-selectable symbols is generally a bad idea. I first tried b) but then ended up redoing the patch from scratch to approach c), so we can also remove the other selects. I checked that CONFIG_I2C is still enabled with davinci_all_defconfig, so that does not have to change.

2015-11-17[media] include/media: split I2C headers from V4L2 coreMauro Carvalho Chehab1-1/+1
Currently, include/media is messy, as it contains both the V4L2 core headers and some driver-specific headers on the same place. That makes harder to identify what core headers should be documented and what headers belong to I2C drivers that are included only by bridge/main drivers that would require the functions provided by them. Let's move those i2c specific files to its own subdirectory. The files to move were produced via the following script: mkdir include/media/i2c (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done And the references corrected via this script: MAIN_DIR="media/" PREV_DIR="media/" DIRS="i2c/" echo "Checking affected files" >&2 for i in $DIRS; do for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do n=`basename $j` git grep -l $n done done|sort|uniq >files && ( echo "Handling files..." >&2; echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done"; ); echo "Handling documentation..." >&2; echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done" ); ) >script && . ./script Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.

We cannot call phy_register_fixup_for_uid() if CONFIG_PHYLIB is not built into the kernel, and we should not enforce that to be built into vmlinux either, because one might want to disable the entire network stack.

2014-02-23ARM: davinci: aemif: get rid of davinci-nand driver dependency on aemifIvan Khoronzhuk1-0/+5
The problem that the set timings code contains the call of Davinci platform function davinci_aemif_setup_timing() which is not accessible if kernel is built for another platform like Keystone. The Keysone platform is going to use TI AEMIF driver. If TI AEMIF is used we don't need to set timings and bus width. It is done by AEMIF driver. To get rid of davinci-nand driver dependency on aemif platform code we moved aemif code to davinci platform. The platform AEMIF code (aemif.c) has to be removed once Davinci will be converted to DT and use ti-aemif.c driver.
