* ar71xx: spi-rb4xx fix.Sergey Sergeev2016-07-021-1/+1
| | | | | | | | In new kernels we should use clk_prepare_enable instead of clk_enable since clk_enable does not make proper initialization that leads to rise WARN_ON messages and not working spi bus on the device. Signed-off-by: Sergey Sergeev <adron@yapic.net>

* ag71xx: replace delay with sleep callsJohn Crispin2014-12-072-6/+6
| | | | | | | | | | | | I don't see that we're in an atomic context so there's no need to busy-wait. Therefore replace the delay with sleep calls. See also Documentation/timers/timers-howto.txt. It states: "In general, use of mdelay is discouraged and code should be refactored to allow for the use of msleep." Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> SVN-Revision: 43539

* kernel: modify mtd related patches for 3.14Hauke Mehrtens2014-05-082-2/+6
| | | | | | | | | | | | The change is the same as ("kernel/generic: modify mtd related patches"). Since these files are under files directory, not a files directory of specific kernel version, better to also change them. So it will avoid adding files to future specific files directory (e.g. files-3.14) for this mtd related change. Signed-off-by: Zhao, Gang <gamerh2o@gmail.com> SVN-Revision: 40732

* ar71xx: ag71xx: increase calculated max frame length valueGabor Juhos2014-01-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The r39147 commit introduces a regression: at lease on some routers with ar8216 switch large packets get lost if 802.1q tagged port is used on the interface connected to the aforementioned switch. The r39147 changes code in the way so interface is set to accept packets no longer than max ethernet frame length for a given mtu. Unfortunately ar8216 has a feature: it sends two additional bytes as a packet header and those this header needs to be added to the max frame length. Otherwise long enough packets get lost. The problem only manuifests itself if interface is used in vlan tagged mode. If interface is untagged then ar8216's header fits into space used by 802.1q tag and not packets are lost. Include two additional bytes in the max frame length calculation to fix the issue. This patch is tested and works with Trendnet TEW-632BRP. Signed-off-by Nikolay Martynov <mar.kolya@gmail.com> Patchwork: http://patchwork.openwrt.org/patch/4656/ [juhosg: - simplify the patch to include the additional bytes of the switch header unconditionally, - change subject and update commit message] Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 39219
* ar71xx: ag71xx: fix max frame length setup of the built-in switchesGabor Juhos2013-12-201-5/+12
| | | | | | | | | | | | | The currently used bitmask of the maximum frame length field is wrong for both models. On AR724x/AR933x the largest frame size is 2047 bytes, on the AR934x it is 16383 bytes. Make the MTU setup code model specific, and use the correct bitmask for both models. Also change the value to the maximum. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 39148
* ar71xx: ag71xx: calculate max frame len register value from the MTUGabor Juhos2013-12-201-3/+15
| | | | | | | | | | | | | | | Set the MAX_FRAME_LEN register to zero in ag71xx_hw_init() and write the correct value into that from the ag71xx_open() and ag71xx_fast_reset() functions. Also recalculate the RX buffer size based on the actual maximum frame length value to optimize memory allocation. Additionaly, disallow to change the MTU value while the interface it running.
