2016-03-10rtl8xxxu: Init H2C command register for 8723buJes Sorensen
In addition make register read/write flow match closer to vendor driver flow. This is mainly to be able to compare the register write log with the vendor driver, and can be optimized later once 8723bu support is working.

2016-03-10rtl8xxxu: rtl8192eu: Map out EFUSE TX power areaJakub Sitnicki
TX power values are laid out differently in EFUSE found in RTL8192EU & RTL8188EU devices. TX power indices and differences for each RF path are not interleaved (A, B, A, B), as in other chips, but follow one another (A, B, C, D).

2016-03-10rtl8xxxu: First stab at adding IQK calibration for 8723bu partsJes Sorensen
The 8723bu also has it's own IQK calibration process. This is similar in flow, but still different enough to warrent it's own implementation, at least for now. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-10rtl8xxxu: Add a couple of new register definitionsJes Sorensen

2016-03-10rtl8xxxu: rtl8xxxu_h2c_cmd(): Add size argumentJes Sorensen
The firmware command API differs slightly between new and old devices. The new generation requires the size since there is no extension bit encoded into the command number. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-10rtl8xxxu: rtl8723bu_parse_efuse(): Use a pointer to the struct rtl8723bu_efuseJes Sorensen

2016-03-10rtl8xxxu: Don't check for illegal offset when reading from efuseJakub Sitnicki
It is enough to check for either illegal offset or illegal map address because map address is a value derived from an offset: map_addr = offset * 8 EFUSE_MAP_LEN = EFUSE_MAX_SECTION_8723A * 8 Leave just the check for an illegal map address because its upper bound (EFUSE_MAP_LEN) is used also in a couple other places.

2016-03-10rtl8xxxu: Add rtl8723bu_radioa_1t_init_tableJes Sorensen
Add 8723bu 1T radio init table. The vendor driver indicates that some registers need special treatment for TFBGA90, TFBGA80, and TFBGA79 packaging. However the vendor driver never actually checks the package type, so just stick to default values here.
