2020-01-06remove ioremap_nocache and devm_ioremap_nocacheChristoph Hellwig1-1/+1
ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Arnd Bergmann <arnd@arndb.de>
2019-01-10bcma: keep a direct pointer to the struct deviceRafał Miłecki1-2/+2
Accessing struct device is pretty useful/common so having a direct pointer: 1) Simplifies some code 2) Makes bcma_bus_get_host_dev() unneeded 3) Allows further improvements like using dev_* printing helpers Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-01-23bcma: use standard bus scanning during early registerRafał Miłecki1-1/+1
Starting with kernel 3.19-rc1 early registration of bcma on MIPS is done a bit later, with memory allocator available. This allows us to simplify code by using standard bus scanning method. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2014-09-30bcma: register bcma as device tree driverHauke Mehrtens1-0/+81
This driver is used by the bcm53xx ARM SoC code. Now it is possible to give the address of the chipcommon core in device tree and bcma will search for all the other cores.

2014-09-09bcma: use separated function to initialize bus on SoCRafał Miłecki1-2/+9
This is required to split SoC bus init into two phases. The later one (which includes scanning) should be called when kalloc is available.

2014-09-09bcma: move bus struct setup into early part of host specific codeRafał Miłecki1-0/+3
This change is important for SoC host. In future we will want to know chip ID (needed for early MIPS boot) before doing cores scanning. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Acked-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-08-28bcma: only map wrapper if its address is availableHauke Mehrtens1-0/+4
The Chipcommon B core does not have a wrap address and it would fail here. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-08-10bcma: make some functions staticHauke Mehrtens1-1/+1
The functions and structs are not used in an other file and the prototypes are in no header file, just make them static so the compiler is able to optimize them better. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-08-08bcma: add SOC busHauke Mehrtens1-0/+183
This patch adds support for using bcma on a Broadcom SoC as the system bus. An SoC like the bcm4716 could register this bus and use it to searches for the bcma cores and register the devices on this bus. BCMA_HOSTTYPE_NONE was intended for SoCs at first but BCMA_HOSTTYPE_SOC is a better name.
