Subject: [PATCH 3/8] mfd: max77686/802: Remove support for board files
The driver is used only on Exynos based boards with DTS support.
Convert the driver to DTS-only version. This simplifies a little the
code:
1. No dead (unused) entries in platform_data structure.
2. More code removed (from all three patches: 34 insertions(+), 107
deletions).
3. Regulator driver does not depend on allocated memory
from MFD driver.
4. It makes also easier extending the regulator driver
Signed-off-by: Krzysztof Kozlowski <k.kozlowski@...sung.com>
