iwlwifi: pcie: enable LP XTAL to reduce power consumption 1. Enable LP XTAL to avoid HW bug where device may consume much power if FW is not loaded after device reset. LP XTAL is disabled by default after device HW reset. Configure device's "persistence" mode to avoid resetting XTAL again when SHRD_HW_RST occurs in S3. 2. Add methods to access SHR (shared block memory space) directly from PCI bus w/o need to power up MAC HW. Shared internal registers (e.g. SHR_APMG_GP1, SHR_APMG_XTAL_CFG)can be accessed directly from PCI bus through SHR arbiter even when MAC HW is powered down. This is possible due to indirect read/write via HEEP_CTRL_WRD_PCIEX_CTRL (0xEC) and HEEP_CTRL_WRD_PCIEX_DATA (0xF4) registers. Use iwl_write32()/iwl_read32() family to access these registers. The MAC HW need not be powered up so no "grab inc access" is required. For example, to read from SHR_APMG_GP1 register (0x1DC), first, write to the control register: HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register) HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 2 (read access) second, read from the data register HEEP_CTRL_WRD_PCIEX_DATA[31:0]. To write the register, first, write to the data register HEEP_CTRL_WRD_PCIEX_DATA[31:0] and then: HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register) HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 3 (write access) Signed-off-by: Alexander Bondar <alexander.bondar@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

iwlwifi: move prph handling into the transport New transports may handle it internally for better performance. Also move the tracing inside PRPH access which will make the output more readable: iwlwifi_dev_ioread_prph32: Read 0x0 from SCD_AGGR_SEL (32-bit) instead of the corresponding accesses to HBUS_TARG_PRPH_*.

iwlagn: move IO functions out of line This generates a massive reduction in module size: with debug: text data bss dec hex filename 670300 13136 420 683856 a6f50 iwlagn.ko (before) 388347 13136 408 401891 621e3 iwlagn.ko (after) without debug: text data bss dec hex filename 528575 13072 420 542067 84573 iwlagn.ko (before) 294192 13072 408 307672 4b1d8 iwlagn.ko (after) This also removes all the IO debug functionality since it can easily be replaced by tracing, and makes the code unnecessarily complex. I haven't done any CPU utilisation measurements, but given that the hotpaths don't use much IO it is not likely to have a negative impact; in fact, the size reduction will reduce cache pressure which possibly improves performance. Finally, an unused function or two were removed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.
