bcma: Replace mdelay with usleep_range in bcma_pmu_resources_init

2018-02-27T13:52:13Z

After checking all possible call chains to bcma_pmu_resources_init() here, my tool finds that this function is never called in atomic context, namely never in an interrupt handler or holding a spinlock. Thus mdelay can be replaced with usleep_range to avoid busy wait. This is found by a static analysis tool named DCNS written by myself.

bcma: support PMU present as separated bus core

2016-02-06T11:36:11Z

On recent Broadcom chipsets PMU is present as separated core and it can't be accessed using ChipCommon anymore as it fails with e.g.: [ 0.000577] Unhandled fault: external abort on non-linefetch (0x1008) at 0xf1000604 Solve it by using a new (PMU) core pointer set to ChipCommon or PMU depending on the hardware capabilities.

bcma: use _PMU_ in all names of PMU registers

2016-02-06T11:36:11Z

PMU (Power Management Unit) seems to be a separated piece of hardware, just accessed using ChipCommon core registers. In recent Broadcom chipsets PMU is not bounded to CC but available as separated core. To make code cleaner & easier to review (for a correct R/W access) use clearer names.

bgmac: driver for GBit MAC core on BCMA bus

2013-01-10T07:37:03Z

BCMA is a Broadcom specific bus with devices AKA cores. All recent BCMA based SoCs have gigabit ethernet provided by the GBit MAC core. This patch adds driver for such a cores registering itself as a netdev. It has been tested on a BCM4706 and BCM4718 chipsets. In the kernel tree there is already b44 driver which has some common things with bgmac, however there are many differences that has led to the decision or writing a new driver: 1) GBit MAC cores appear on BCMA bus (not SSB as in case of b44) 2) There is 64bit DMA engine which differs from 32bit one 3) There is no CAM (Content Addressable Memory) in GBit MAC 4) We have 4 TX queues on GBit MAC devices (instead of 1) 5) Many registers have different addresses/values 6) RX header flags are also different The driver in it's state is functional how, however there is of course place for improvements: 1) Supporting more net_device_ops 2) SUpporting more ethtool_ops 3) Unaligned addressing in DMA 4) Writing separated PHY driver Signed-off-by: Rafał Miłecki Signed-off-by: David S.
