2015-04-23debug-mmrs: Eliminate all traces of the USB_PHY_TEST MMRAndre Wolokita1-1/+0
Interacting with the USB_PHY_TEST MMR through debugfs was causing wide-spread chaos in the realm (kernel panic). Expunge all references to this demonic register. Signed-off-by: Andre Wolokita <Andre.Wolokita@analog.com>
2014-03-09i2c: bfin-twi: move bits macros and structs in header from arch include to ↵Sonic Zhang1-0/+1
generic include The ADI TWI peripheral is not binding to the Blackfin processor only. The bits macros and structs should be put in the generic include header. And update head file path in drivers accordingly. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2012-05-21blackfin: add bf60x to current frameworkBob Liu1-3/+6
This patch added bf60x to current blackfin kernel framework. Signed-off-by: Bob Liu <lliubbo@gmail.com>
2011-07-23Blackfin: debug-mmrs: generalize pint logicMike Frysinger1-19/+31
Don't bind the code to specific CPU defines. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: bf54x: tweak MMR pint namesMike Frysinger1-1/+1
The hardware block uses the name "request" rather than "irq", so update the struct accordingly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: debug-mmrs: use new gptimer_group layout to simplify codeMike Frysinger1-18/+34
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: debug-mmrs: prevent macro arg from expandingMike Frysinger1-1/+1
Passing a non-simple expression in as the addr arg could incorrectly apply the pointer cast resulting in misbehavior. Add proper paren. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: debug-mmrs: disable PERIPHERAL_MAP for IMDMA channelsMike Frysinger1-1/+2
The documentation for the IMDMA channels appears to be incorrect. These DMA blocks don't actually have PERIPHERAL_MAP MMRs for us to access. Attempts to do so lead to system mmr hardware errors. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-05-28Blackfin: debug-mmrs: include RSI_PID[4567] MMRsMike Frysinger1-0/+4
The documentation is a little iffy as to whether these are actual MMRs, but reading them on the hardware works, and the previous version of this logic (the SDH) had PID[4567]. So add it for RSI too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-05-28Blackfin: debug-mmrs: fix typos with gptimers/mdma/ppiMike Frysinger1-18/+14
This code was mostly developed against a BF54x, so some BF537-specific issues were missed. The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse of the EPPI block). The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG. Seems the sim does not catch misreads here so that'll need to get fixed. The gptimer block is mostly 32bit regs, not 16bit. Use the gptimer struct to figure that out rather than hardcoding it locally. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
