PATCH 1/1 ARM: DRA7: beagle-x15: hwmod: Fix boot crash with DEBUG_LL

With commit '7dedd34: ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL' we moved from parsing cmdline to identify uart used for earlycon to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS.

On beagle-x15, we use uart3 for console and missed enabling this flag for uart3 hwmod, so boot fails with DEBUG_LL. Enable DEBUG_OMAP4UART3_FLAGS for uart3 hwmod.

For using DEBUG_LL, enable CONFIG_DEBUG_OMAP4UART3 in menuconfig.

PATCH 1/1 ARM: DRA7: beagle-x15: hwmod: Fix boot crash with DEBUG_LL

$subject should probably need a cleanup: this is hwmod support for DEBUG_LL on UART3 - x15 happens to be one of the platforms that uses that, but not the only one.. I suggest removing x15 from $subject and rephrasing accordingly.

for uart3 hwmod, so boot fails with DEBUG_LL. Enable DEBUG_OMAP4UART3_FLAGS for uart3 hwmod.

Could you align your commit message to 70 chars if possible?

what's the difference ? why do you want that many more characters if those 7 are enough for git to find a uniq commit ? Try this:

$ git show --abbrev-commit 90020c7b2c5e02200bc752c8cfeba91c4435588c

alright, if it's Documented, it's best done ;-)
